The method unloading of massif around working at the longwall mining system inclined seams of Donbass

The problems of the protection and maintenance of district preparatory workings in the unloading zones for example diamond mines Almazno-Marievski geological and industrial region of Donbass. The mining are analyzed for the study of rock pressure on the circuit mine workings. The simulation of these geological conditions, the analysis, characterizing the influence of the discharge cavity on the stability preparatory working support. Constructed diagrams of stresses and strains, revealing unloading effect on the development at the longwall mining system of inclined coal seams.
