摘 要:针对大倾角煤层工作面围岩力学运移规律复杂,围岩应力和矿压数据采集分析困难的问题,本文以某煤矿220705工作面为研究背景,以支架电液控矿压数据作为矿压分析基础,对工作面顶板的矿压特征和矿压分布区域进行了分析,并通过区域划分制定了不同区域的来压判定值标准,实现了综采工作面煤层开采过程中工作面综采区域矿压分析及预警研究。In view of the complex mechanical movement law of surrounding rock in the working face of large inclined seam and the difficulty in collecting and analyzing the surrounding rock stress and ground pressure data,this paper takes the 220705 working face of a coal mine as the research background,and takes the electro-hydraulic control ground pressure data of the support as the ground pressure analysis basis,analyzes the ground pressure characteristics and the ground pressure distribution area of the working face roof,and formulates the criteria for determining the value of incoming pressure in different areas through regional division,Realized the analysis and early warning research on the ground pressure of the fully mechanized mining area in the process of coal mining in the fully mechanized mining face.
