Abstract

<jats:title>Abstract</jats:title><jats:p>Results of experimental tests aiming at determination of base pressure on the floor, carried out within “Geosoft” project, are presented. The tests included stand tests carried out with use of unique measuring instrumentation and special hydraulic cushion as well as tests of load of roof support set to load in operating longwall panel. The measurement results confirmed the necessity to consider the 3D model of cooperation of base and floor. Factors having impact on distribution of base pressure on the floor and its maximal value were identified, taking into account the test results.</jats:p>
