综采面过断层施工技术及安全技术措施研究

Study on construction technology and safety technical measures of fully-mechanized mining faces passing through faults

20103综采工作面条件复杂,断层严重影响工作面的推进,在特殊情况下需要提前沿断层构造段掘进空巷。研究了断层段掘进的关键技术,介绍了断层的基本情况、过断层技术施工方案以及过断层安全技术措施,提高了工作面推进速度,确保了顶板稳定性,为以后类似条件下工作面的回采推进提供了实践经验。

The comprehensive mining face conditions were complex, and the fault seriously affected the propulsion of the working face. Under special circumstances, it was necessary to dig into the empty roadway along the fault structural section in advance. This paper studies the fault section of the key technology of excavation, this paper introduced the basic situation of the fault, fault technology con- struction scheme and safety technical measures of a fault, the research improved the working face advancing speed, ensure the roof sta- bility, for the similar working face under the condition of stope advance provided practical experience.
