三道沟煤矿大采高开采覆岩来压规律研究

Study on the overlying strata pressure law with large mining height in Sandaogou Coal Mine

以实用矿山压力理论作为指导,通过矿压观测试验及理论研究,对三道沟煤矿首采的大采高85201工作面的覆岩运动规律进行了系统地分析。

Based on the study of ground pressure observation experiment and theory,the paper systematically analyzed the overlying strata pressure law of 85201 first mining face with large mining height in Sandaogou Coal Mine.
