Abstract
This design is the new shaft of the Mt/a to Dayan
This mineral zone inside has 3 lamella coal whole zones can adopt, average thickness in coal seam is meters, strike length is , dipto length ~, average rake angle in coal seam is 14 adopt to keep quantisty as , can adopt time limit as design adopts the well two levels expand, dividing the line eight adopt the zone, a the level can return to adopt the 101, 201the zone, the adoption concentrates the big lane arranges, one alignment lengthways the wall adopts the method of coal adopts the coal, synthesizing the mechanization return to adopt the the way is a central margin type to ventilate. the technology of coal mining adopts prehensive mechanization technology of coal mining.
Keywords: Inclined dhaft development Mining technology Inclined longwall coal mining method
