Mining Technology Practice Under Complex Geologic Structure Working Face
Abstract：Through reforming roadway,the study aims to optimize the working face layout.by moving parts of face's equipments,the mining face passes through fault F131 with a drop height of 18 m.Based on the treasonable blasting parameters,the study carries out the concussion blasting to break top to pass through DF20 fault with a drop height 7.7 m.These two methods are applied successfully in the same work-face to lighten the effects from the complicated geological conditions towards mining,reduce frequency of fully mechanized mining coal work-face removing,achieve continuous mining and improve the recovery coefficient.
