Fully Mechanized Mining Safety Technology for Large-dip Angle Coal Seam

The factors, including coal wall caving and falling, mined coal and waste rock rolled along the floor, glide of conveyor and support, have brought great difficulties to the application of fully mechanized mining technology in large-dip angle coal seam. Zhangcun Coal Mine smoothly realizes safe production of large-dip fully mechanized mining face through comprehensive measures including oblique construction, coal wall shallow hole injection, anti-caving and anti-rolled.
