穿八里铺断层施工立眼水文地质情况分析与实践
|
摘要
矿井下穿大型断层区域工程施工,面临着断层导水性分析、施工地层富水性分析、施工过程控制等相关问题。论述了一个具体地质体条件下工程措施的选择问题,针对断层的水文地质性质分析探查结果,选择了立眼位置方案,提出了安全穿断层的技术措施并最终保证了工程的安全施工。通过济宁二号煤矿穿八里铺断层施工回风立眼工程实例,为此类工程方案选择及实施提供一定的实际参考。
The underground construction across a large fault area faces problems such as fault conductivity analysis, water abundance analysis of strata under construction and construction process control. This paper discusses the choice of engineering measures under the conditions of a specific geological body. According to the results of the hydrogeological properties analysis and exploration of fault, the scheme of vertical hole position was chosen, the technical measures to safely cross the fault was proposed and finally the safe construction of the project was ensure. This paper provides some practical reference for the selection and implementation of this kind of engineering scheme through the example of the vertical holes in air return roadway.
