综采工作面过断层技术实践

Technical Practice of Fault Crossing Technology in Fully Mechanized Mining Face

以14218工作面的F12和F13断层为对象,对快速过断层采煤技术进行了研究。对断层带附近的煤岩注射马丽散加固顶底板,并制定工作面过断层的安全技术措施。实践应用效果表明:14218工作面顺利通过F12和F13断层,开采中无安全事故发生,产生了较好的经济效益。

Taking F12 and F13 faults of 14218 working face as objects, this paper studies the technology of rapid cross-fault mining. The roof and floor are strengthened by injecting Malisan into coal and rock near the fault zone, and the safety technical measures for crossing the fault are formulated. Practical application results show that 14218 working face passes through F12 and F13 faults smoothly, no safety accidents occur in mining, and good economic benefits are produced.
