摘　　要：为摸清15211综采工作面顶板的活动规律及矿压显现特征,评价支架对工作面顶板运动的适应性,为工作面顶板管理、支护强度的确定提供科学依据,因此需要对该面整个回采过程进行连续的矿压观测。本次观测分析,将对工作面回采期间的矿压信息进行分析,从而得到反映顶板活动规律和支架适应性分析的相关技术参数,同时也可为相似顶板条件的工作面的开采支护设计提供参考依据。In order to find out the activity rule and the characteristics of the mining pressure of the fully mechanized mining face of 15211,evaluate the adaptability of the support to the roof movement of the working face,and provide scientific basis for the management of the roof and the determination of the support strength of the working face,it is necessary to conduct continuous mining pressure observation on the whole mining process of the face.This observation analysis will analyze the ore pressure information during the stoping of the working face,so as to obtain the relevant technical parameters reflecting the roof activity rule and the analysis of the adaptability of the support.Meanwhile,it can also provide reference for the mining support design of the working face under similar roof conditions.
