摘要
通过分析峰峰集团万年矿13902工作面的顶板岩性,绘制了井下压力表数据折线图。结合工作面现场记录的问题,判断出该工作面的老顶运动形式为"缓慢下沉",并对其运动及矿压规律进行了总结和研究。
Through the analysis of roof rock in Fengfeng group Wannian mine 13902 working face, drawing downhole pressure gauge data line graph. Combining the work field records, determine the working face roof movement in the form of ＂slow sinking＂, and the motion and mine pressure regularity were summarized and studied.
