Loading characteristics of support sections were identified during the gradual subsidence of roof rock onto previously collapsed sections. It was also established that tensile stresses along the roof contour can cause cracks, forming steps in its profile. This process continues to the ground surface, increasing rock pressure at the face by up to 72%. Prevention of the consequences of this phenomenon is achieved by chamber mining, in which experimental data are measured, and the state of the face is calculated in each mining cycle. To design the new technology, an information system was created that accounts for the effectiveness of work scenarios, considering geological disturbances and the machine's turnover to the next mining section. This minimizes the duration of the technological mining cycle in each scenario. For chamber mining, the transport chain length in the stope unit is 1.27 times shorter. Capital costs are three times lower than for long wall mining The challenge of developing inclined and steep coal seams, whose reserves are comparable to those of already mined coal, has also been addressed.
