大倾角厚煤层放顶煤综采工艺分析

摘要

该文分析大倾角煤层开采过程中上覆岩层的应力分布及运动变化，分析综采设备在工作面的受力情况及提高稳定性的方法、措施和论述如何高效放顶煤。分析结果对大倾角煤层的安全、高效和经济开采的研究有一定的参考意义。%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.
