STRATIFICATION ASSESSMENT OF ROOF ROCKS AT COAL SEAM MINING
A numerical model of a coal seam with enclosing rocks was created. Numerical modeling of the stress-strain state was carried out and revealed some regularities of roof rock stratification during the mining of a coal seam.
Stress-strain state, roof collapse, numerical modeling, gaping cracks, boundary
conditions, the coal seam, longwall.
