TECHNOLOGICAL SOLUTIONS FOR INTENSIVE WORKING OF MEDIUM THICK INCLINED COAL SEAMS IN DIFFICULT CONDITIONS IN THE MINES OF THE QUANG NINH COAL BASIN

Thang P.D., Thang H.H., Phuc L.Q.

Analyzed the promising direction of implementation of the state plan for the extraction of coal in Vietnam largely depends on the efficiency of further industrial development of the potential of the Quang Ninh coal basin. An analysis of the limitations of the application of technologies, depending on the complexity of the mining geological and mining technological conditions of the Quang Ninh coal basin, is given. Analyzed the possibility and feasibility of using the room and pillar method based on the analysis of foreign experience in mining coal seams. An innovative technological scheme of highly efficient mining of medium thick inclined coal seams with a diagonal disposition of the line of face with the use of self-moving supports along articulated joints was proposed. A block diagram of the choice of mining method is based on the angle of dip classification of coal seams.
