8231机巷综掘快速过断层的措施研究
|
摘要
团柏煤矿8231机巷过FX11断层,该断层落差近6m造成施工困难。本文对8231机巷过FX11断层进行了实践应用研究,通过准确定性、精确定位,采用人工干预措施,提前刹底撵煤,减少破矸量。实践应用效果表明:8231机巷顺利快速过FX11断层,通过效益对比分析可知该施工方案取得了很好的经济效益。
The 8231 machine roadway of Tuanbai Coal Mine passes through the FX11 fault, and the drop of the fault is nearly 6m, which makes the construction difficult. In this paper, 8231 machine roadway crossing FX11 fault has been applied in practice. Through accurate qualitative and precise positioning, manual intervention measures are adopted to drive out coal ahead of time and reduce waste. Practical application results show that 8231 machine roadway passes through FX11 fault smoothly and quickly. Through the benefit comparison analysis, it can be seen that the construction scheme has achieved good economic benefits.
