Probability distributions ofthe driving costs can be used in stochastic simulation ofthe costs related to execution of roadways, which are designed for similar (comparable) geological - mining conditions, in order to assess the cost level, as well as to determine risk of its overrunning.}, title={Principles of data bases creation for stochastic simulation of driving costs of roadways in hard coal mines}, type={Article}, URL={http://journals.pan.pl/Content/133727/PDF-MASTER/7_GSM_23_4_2007_Magda_Principles.pdf}, keywords={hard coal mining, economic and financial data bases, underground roadways}, }
