摘要
在煤矿矿井井筒建设过程中,遭遇采空区是不可避免的事情。采空区可能导致围岩强度降低,并对井筒建设产生不利影响。针对某矿井井筒工程及井筒附近的煤层采空区,首先对该工程做出简单介绍,之后阐明采空区对井筒建设影响的类型和机理,最后讨论了当井筒穿越采空区时对采空区的处理原则和具体方法。
In the construction process of coal mine shaft,it is inevitable to encounter goaf.The goaf may lead to the decrease of surrounding rock strength and have a negative impact on the shaft construction.In view of a mine shaft project and the coal seam goaf near the shaft,this paper first makes a brief introduction to the project,then clarifies the type and mechanism of the influence of the goaf on the shaft construction,and finally discusses the treatment principle and specific method of the goaf when the shaft passes through the goaf.
