METHOD FOR PREPARING INITIAL DATA FOR SOLVING TWO-DIMENSIONAL NUMERICAL MODELING PROBLEMS OF NON-UNIFORM ANGULAR TARGETS
Abstract
Modern underground coal mining technologies are characterized by the intensification of coal extraction processes in longwall mechanized longwalls (LWLs), typically mining flat, medium-thick coal seams. To ensure efficient and safe preparation and development of coal seams, a multi-entry mining system is used, leaving coal pillars up to 60 m wide between workings. This leads to inefficient use of the subsoil and losses of up to 40% of the estimated reserves. Smaller pillars collapse under the influence of rock pressure, and production stops due to a reduction in the cross-section of the adjacent workings.
