摘要
经对芦子沟煤矿采空区极近距离下部煤层首采工作面的矿压显现特征观测,综合掌握相应地质条件下工作面来压特征及其液压支架的受力状态,分析了工作面的适应性,为工作面安全回采、顶板管理提供技术支持。
On the observation of strata behaviors of Luzigou mine, the pressure of the working face and the The adaptability of the working face was also studied, mining and roof management. the first mining face of ultra-close lower coal seam in stress condition of hydraulic support were controlled. which could provide technological support for safety
