摘要
针对回坡底煤矿10-109工作面过断层期间推进度低、机组负荷大的问题,确定采用CO_2爆破致裂技术解决工作面过硬岩断层的问题,并提出了相关爆破方案与安全措施,能够有效满足现场处理的需要,为相似条件回采或掘进工作面过硬岩段提供了工程实例。
Aiming at the problems of low mining speed and large unit load of No. 10-109 working face in Huipodi coal mine during passing through fault, the CO2 blasting fracturing technology was proposed for working face to pass the hard rock fault, and the relevant blasting schemes and safety measures were put forward, which can provide engineering guidance for mining or drilling face passing through hard rock area in similar conditions.
