不规则块段采煤工艺优化及支护方法选型

摘要

According to the coal seam occurrence conditions of 23206 working face ,Chaili Coal Mine optimizes the triangle block design, change the original design of high-grade conventional mining into irregular fully mechanized working face, compared with high-grade conventional mining process (mining height 2.0m) can recover the remaining 3 coal with thickness 0.9m, recovering coal amount to about 42000 T, at the same time provides valuable experience for the fully mechanized working face layout in triangle block in the future.%柴里煤矿根据23上206工作面的煤层赋存条件，优化三角块段工作面设计，将原来计划采用的高档普采工作面设计成不规则的综采工作面，与采用高档工艺（采高2.0m）相比，可将残余的0.9m煤炭回收出来，可多回收煤炭资源约4.2万t，为今后在三角块段布置综采工作面提供了宝贵经验。
