摘要
Abstract
Most coal seams of coal field in Western China are large inclined angle. The overlying strata stress distribution and movement were analyzed in this paper during the large dip angle coal seam mining process , and then the stress conditions of the working face and the method and measures that improve the stability were discussed, the analysis results have a certain reference value for the safety, high efifciency and economic exploitation of large dip angle coal seam.关键词
