INVESTIGATION OF THE STABILITY OF MINE WORKINGS IN DIFFICULT MINING AND GEOLOGICAL CONDITIONS
As a result of the studies carried out, it has been established that when devel- oping coal seams in difficult mining and geological conditions at great depths due to the strat- ification of the roof rocks, the danger of emergencies arises from collapses of lateral rocks. The lining massif or wide flexible supports used to protect mine workings under such condi- tions support the rocks of the main and immediate roof as a result of their stratification and eliminate the negative phenomena manifested as a result of their sudden collapse.
