The main optimized objects in underground mines include: stope layout, access layout and production scheduling. It is common to optimize each component sequentially, where optimal results from one phase are regarded as the input data for the next phase. Numerous methods have been developed and implemented to achieve the optimal solution for each component. In fact, the interaction between different phases is ignored in the tradition optimization models which only get the suboptimal solution compared to the integrated optimization model. This paper proposes a simultaneous integrated optimization model to optimize the three components at the same time. The model not only optimizes the mining layout to maximize the Net Present Value (NPV), but also considers the extension sequence of stope extraction and access excavation. The production capacity and ore quality requirement are also taken into account to keep the mining process stable in all mine life. The model is validated to a gold deposit in China. A two-dimensional block model is built to do the resource estimation due to the clear boundary of the hanging wall and footwall. The thickness and accumulation of each block is estimated by Ordinary Kriging (OK). In addition, the conditional simulation method is utilized to generate a series of orebodies with equal possibility. The optimal solution of optimization model is carried out on each simulated orebody to evaluate the influence of geological uncertainty on the optimal mining design and production scheduling. The risk of grade uncertainty is quantified by the possibility of obtaining the expected NPV. The results indicate that the optimization model has the ability to produce an optimal solution that has a good performance under the uncertainty of grade variability.

In the Polish spatial planning law one of basic principles is to preserve spatial order. However, the analysis of the law and its implementation show, that instead of spatial order, overall circumstances promote disorder. The analysis covers the law adopted in 2018, which aimed at boosting the development of housing. Findings show, that the new law may rather promote chaos in urban space. One of the drawbacks is undermining of the spatial order by creating the possibility of adopting resolutions pertaining to housing and accompanying services, that are contradictory to provisions of master plans.

The first post-war, comprehensive Gdynia Downtown Plan was at the same time one of the first spatial development plans in Poland defining the directions of transformation of multifunctional downtown structures in the new system and legal realities. It was the Plan of the Polish Breakthrough related to the realities of the downtown area of Gdynia. The study area included the Gdynia Valley limited by the hills of Kamienna Góra, Redłowo and Chylońskie Forests with the development of a complete pre-war city developing in accordance with the fi rst plan of Adam Kuncewicz from 1925 in the zone of 3 km, counted from the center of the inner port. The aim of the plan was to look for centralizing potential in the fi eld of research. This concept was treated as a power degree related to the then existing state, as well as the possibility of further development or transformation.

This paper presents a synthesis of research in the field of social activity in development of urban public spaces. Interest in social participation in which many groups sees a remedy to the problems of the city - including spatial chaos - has many causes. One of them is the lack of trust in the social side to the profession of architecture. The article indicates the possible cause of this state for which it was flawed legislation and the planning system, which in practice is not conducive to the formation of order, harmony and beauty, but facilitate the implementation of the narrow groups of interests, bringing the rank of designer as creator of the role of the investor's decision executor.

The basic resource of urban planning is space, which as a result of transformation has a direct impact on socio-economic development and quality of life. The author’s purpose was to define planning solutions for urban spatial policy, which can raise the quality of living, especially in the residential environment. In connection with the above, the literature of the subject was analysed and examples of good spatial policy and urban development in the living environment were shown. Particular attention was paid to the planning solutions in Paris and Vienna, as well as to the examples of the new living environment creation in some Scandinavian cities.

Maritime spatial planning is quite a new field that emerged as an idea only after 2000, with the first practical implementation after 2010. In Polish legislation, the first entries regarding the possibilities of this type of planning appeared in 2003. For the next ten years resources of necessary knowledge and human competences had been created. In this way, a considerable amount of knowledge in the field of maritime spatial planning was accumulated in Poland, and our country has become one of the leaders in scientific research in this field. Poland has enriched the MSP methodology and has proposed many new and pioneering solutions. In 2016, the Directors of Maritime Offices began developing a coherent draft of maritime spatial plan for Polish maritime areas in the part relating to the exclusive economic zone, the territorial sea and parts of internal sea waters (including the Gulf of Gdańsk) on a scale of 1: 200,000. The work on the preparation of this draft plan was coordinated on behalf of all offices by the Director of the Maritime Office in Gdynia, and the work was assigned to a Consortium consisting of the Maritime Institute in Gdańsk and the Maritime Fisheries Institute – National Research Institute in Gdynia. The Polish plan is included in the top ten plans in the world and is one of the first to have a decision-making and not indicative character. The Polish planning process has resulted in the development of many innovative solutions that are worth wider dissemination. The presented study aims to identify key problems and formulate conclusions regarding spatial planning of Polish maritime areas, as well as to propose the most important directions for further planning work. The analytical material that is the subject of the study are experience and solutions adopted in our country for maritime spatial planning.

The subject discussed in this paper is the evolution of the ideas of organic development in urban planning, focused on the waterfront areas. The paper also aims to analyze and interpret current trends in urban water waterfront planning, which are infl uenced by the contemporary ideas related to environmental issues, landscape planning, new technologies in the fi eld of building design and civil- and hydroengineering or application of the renewable energy sources.

The main purpose of this article is to present facts related to the history of Port Praski located on the right bank of the Vistula river in Warsaw, which is currently being built. The subject of the consideration is the area and development of the former Port Praski, which project and the fi rst works began after the First World War. It’s spatial and functional connections with the downtown area and surroundings are also key issue. The article presents plans, concepts, projects and investments, furthermore theirs level of implementation. Signifi cant eff ort was made to answer the research questions concerning social expectations regarding the function and the direction of Port Praski development. In the final part of the article was made a comparison of existing revitalization works in Port Praski with HafenCity – the district of Hamburg, where the revitalization project has been already implemented for 20 years. However, comparative analysis revealed several signifi cant differences, allowed to conclude that Polish model of revitalization is only a partially identical with the approach applied in Western Europe.

The article attempts a comparison of two harbor districts, in Gdansk and in Hamburg. In 2013, a multiannual program - IBA Hamburg (International Building Exhibition) - was completed. The IBA, initiated with the a concept of the Leap over the Elbe River, part of the Growing City development agenda, addressed the problem of restructuring the port-nearby zones in Harburg and Wilhelmsburg, which have been recognised as areas of high potential in metropolitan development. The concept of metrozones (intra-peripheries or intra border zones), similarly to the term in-between City (German: Zwischenstadt), describes the current problems associated with the strive for creation of an original, but efficient and compact European city. Restructuring of the harbor districts enables new development of the urbanized, but never planned as urban space, areas. Shaped in accordance with the technological capabilities and with the regulation standards and norms of the second half of the 20th century, nowadays the areas form the resultative landscape, burdened with the image of an unfriendly or even dangerous zones. In the era of high technology, metrozones are becoming valuable intra-city developmental areas, opened to alternative urban programs, avoiding the homogenising global trends. In connection with the above, the article describes the situation of the area organized around Nowy Port in Gdansk.

The article presents basic changes introduced in the first edition of the governmental Urban Planning and Building Code. The changes regard spatial development, especially planning and permit documents, and competences of the governmental bodies in accepting, legislating and issuing such documents. In this respect, the article points out important regulations for the mining industry, in particular for deposit protection and the initiation of mining projects. In certain cases, critical opinions of some of the governmental institutions are mentioned. In a new document regarding the “Spatial Development Study of a Community”, the draft of the Code orders a division of the community into functional zones. Therefore a mining and extractive industry could be delimited as a functional zone. The Code also specifies that while delimiting a new urbanization area, the documented mining deposits areas should be avoided. In relation to the local spatial plan, the Code establishes the following: in documented strategic mining deposit zones the initiation of non-public purpose investments can only be carried out according to the urban spatial plan. This project also orders that only the local spatial plan can allow for the localization of “establishments that carry a risk of serious industrial breakdown” and “investments that can seriously impact the environment”. The Code also introduces another innovation: the possibility of issuing the local spatial plan with an integrated evaluation on the environmental impact. The “investment permits” are intended to replace both the previous building permits and previous decisions on the conditions of development of the areas not covered in the local spatial plans. The investment permits referring to mining establishments will be issued by the mining administration authorities. The main adverse change for mining is that the exploration of mining deposits owned by the State Treasury loses its previous status of public purposes. The article also indicates that some of the described regulations might be changed during the further legislation process.

The article presents how multi-layered urban lighting projects fit into the programs of integrated activities to improve the living conditions of the local community, the surrounding space, and its economic relations. The role of the electric lighting in revealing the night image of the city, its promotion and public spaces transformations offering new impressions to city residents is growing thanks to the use of the SSL technology. The authors focus on a role of outdoor lighting projects in urban regeneration within the selected urban areas. The paper describes how conscious shaping of lighting by analysing the goals and stages of the project can contribute to the improvement of quality in the processes of renewal of degraded urban areas.

In the paper author discusses problems related to the leading role of architectural structures, as a part of the creating process within contemporary urban space. Architectural objects establish a continuous dialogue not only with their surrounding space, but also between each other. In this relation, the first plan comes with two factors, determining all spatial and functional solutions: the place in which a given project is localized and the time in which the urban designer came to the architect to create his plan. Based on the analysis of own projects and urban and architectural realizations, the author proves that the architectural dialogue in urban space must be respected in the context of the place and the time, but also in the creators moral responsibility. This responsibility is defined by consequences of design decisions not only for the urban space itself, but above all, for people and their coexistence with the space. For designers it reveals a necessity to comply principles of ethics and professing the value system in order to taking care of the urban space not only three-dimensional, but also “existential”.

The aim of the article is to present the problem of revitalization of marketplaces in the context of the challenges they face in contemporary socio-economic conditions. This issue was developed based on desk research and inquiry conducted on a representative marketplace in Gdańsk Oliwa. They served to formulate guidelines for the implementation project aimed at improving the image and economic condition of traditional marketplaces in Poland. Despite significant importance for the local economy, traditional marketplaces are not able to compete with shopping malls and shopping centers, as a result of which they become unsustainable. The ongoing degradation of marketplace areas reduce their attractiveness and role they play in public spaces network. The authors of the project recognize that the solution to the issue of marginalization of traditional marketplaces is to strengthen their image in both physical and media realms. One of the proposed solutions is institutional support for marketplaces by non-governmental organizations involved in the revitalization and aestheticisation of urban areas.

The Hamburg’s policy, as part of the ‘Leap over the Elbe River’ strategy, is an example of the current direction of the city’s renewal, falling beyond classical revitalization. Improvement of quality and refinement of urban structures require an unconventional approach in the problem areas, both in the phase of setting the target standards and at the stage of solution implementation. The districts located in the fork of the Elbe river, Hamburg’s left-bank post-habor areas, were given the IBA (International Building Exhibition) Hamburg status in 2006-13. The area of Wilhelmsburg has become the place of implementing an innovative urban strategy, under the slogan of a renewable city, which has prepared the Island for a modern policy of compact city model development. The conclusions from the analysis of the renewal process that had been carried out within the framework of the IBA Hamburg, described in this article, have been summarized with regard to the Polish conditions represented by the example of the revitalization process in the Nowy Port district in Gdańsk.
