摘要
王楼煤矿3上煤层开采过程中有多个工作面曾发生离层突水,为确保矿井安全高效生产,减少离层水害对矿井的影响。在分析矿井地质条件的基础上,运用关键层理论分析方法,对3上煤层采动后造成的覆岩移动破坏规律进行研究。得出王楼煤矿产生的可积水离层空间位于岩浆岩下部与侏罗系底部。
In the 3 coal seam mining of Wang Lou coal mine,separation of water from layers has occurred in several working faces,in order to ensure the safe and efficient production of the mine and reduce the influence of the separation of water on the mine. Based on the analysis of mine geological conditions,the key strata theory analysis method is used to study the law of overlying strata movement and failure caused by the mining of 3 upper coal seam. It can be concluded that the space of water accumulation in the Wang Lou coal mine is located in the lower part of the magmatic rock and the bottom of the Jurassic.
