Abstract:

After analyzing the geological conditions, aggregate reserves, as well as analyzing the current State.,of the minịng technologies in some mines of the North Eastr Corporation, the paper has evaluated and synthesized all the characteristics of the geologicai conditions, the aggtegate ciassiíication of reserves according to the thickoess and slõpe angle of -the coal seams of the North East Corporation, aị*. the same time, mention the shortcomings of existing mining technologies are being app'lied at some mines in the Corporation. As a result, the paper proposes ãppropriaíte for technicál and technological solutions to improve the output of faces. This technical and technological solutions atter application in practice has achieved good results, they are effective in exploitatỉon each area with speciíic geological conditions, the face achieve stable output, to tormulate important technical and technological solutỉons in exploitation the face at some underground mines of the North East Corporation.
