摘要
以某矿1300工作面为研究对象,分析了工作面回采过地质构造带时断层、陷落柱等影响机制,并对回采工作面过地质构造带技术研究,采用爆破破岩技术进行工作回采,并及时对工作面支护、卸压以及防突水,避免工作面过地质构造带时出现安全事故,保障工作面安全回采。
Taking 1300 working face of a mine as the research object, this paper analyses the influence mechanism of faults and subsidence pillars when working face passes through geological structure zone, and studies the technology of mining face passes through geological structure zone. Blasting rock-breaking technology is used for working mining,and timely support, pressure relief and water inrush prevention are carried out to avoid safety accidents when the working face passes through the geological structure zone and to ensure safe mining of the working face.
