西铭矿42208工作面过断层工艺探讨

Discussion on Technology of Crossing the Fault of 42208 Working Face in Ximing Colliery

西铭矿42208工作面在推进工程中遇到F214逆断层,断层落差为5.5~10 m,倾角为17°~25°,断层贯穿整个工作面,对回采工作影响很大。为保障矿井安全高效生产,决定采用挑顶拉低、一次装药一次爆破的方法快速通过断层,并给出工艺技术和安全措施,在滚帮严重时,采用注浆的方法及时处理,为相似条件工作面快速通过断层提供一定借鉴意义。

The 42208 working face of Ximing Colliery encountered the F214 reverse fault in the propulsion project,whose drop was 5.5~10 m and the dip angle was 17°~25°.The fault penetrated the whole working face and had a great impact on the mining work.In order to ensure the safe and efficient production of mines,the method of picking up and pulling down and blasting once was adopted to quickly pass through the faults in the paper,and the process technology and safety measures were also given,which provided a certain reference for rapid passage through faults.
