Technique of Roadway Layout of Fully Mechanized Mining with Sublevel Caving Stope in Boundary Coal-Pillars Effected by Faults
In order to study the faults effects on the pressure in fully mechanized mining with sublevel caving stope in boundary coal-pillars, the roof structure of it was analyzed and the parameters were estimated in this article, then pressure calculation models of stope in boundary coal-pillars near faults in normal circumstances and encountering faults were established. The support pressure of the stope encountering faults is three times greater than the largest caving support resistance estimated at present. The promoting direction of stope in boundary coal-pillars should avoid being perpendicular to fault strike. Inspired by the conclusion, mine pressure severe appearance during exploitation process can be avoided by optimizing stope roadway layout in boundary coal-pillars.
