摘要
以上湾煤矿12301工作面过上层集中煤柱为工程背景,采用理论计算和数值模拟等手段,分析了集中煤柱下工作面回采的矿压规律,并通过现场仪器实时监测顶板压力的变化,经过分析,掌握了过集中煤柱的矿压规律,为后续工作面过集中煤柱提供了经验。
The 12301 working face of Shangwan coal mine is the engineering background, and thetheoretical calculation and numerical simulation are used to analyze working face pressure regularity ofthe centralized control of coal pillar in upper coal. Meantime, the pressure change of the roof ismonitored at real time by field instrument. By analysis, masters the regularity of the working facepressure of through the concentered of coal pillars, and provides experience for the follow-up face.
