摘要
为全面、系统地研究新安煤业公司主采煤层3煤层采动过程中矿山压力分布情况及采场围岩运动规律,以新安煤业公司3上303综采工作面开采的地质和技术条件为实例,研究制定矿压观测方案,进行观测。
In order to study on the distribution of strata pressure and movement law of surrounding rock of Xinan No. 3 coal, No. 3up303 fully mechanized long＇wall mining face in Zhuanlongwan Mine was taken as the engineering background. A minestrata pressure observation plan was designed and a site observation was conducted.
