煤矿断层防水煤柱留设研究

Resrarch of Mine Coal Fault Waterproof Pillar Preserve

以平舒煤矿断层不导水与断层活化导水的两种地质状态下留设防水煤柱为研究对象,首先分析了下盘工作面对盘太灰含水层、盘一、盘二、盘三含水层注浆前、后不同状态下的断层防水煤柱宽度,接着分析了断层导水时,不同安全系数下断层防水煤柱的宽度,这些工作为保证煤矿的安全开采奠定了基础。

Taking the two geological conditions of Pingshu coal mine fault unguided water and the fault activation guide water for waterproof pillar preserve as the study object,firstly analyzed the footwall work face plate is too grey aquifer, plate under three different states before and after aquifer grouting of fault waterproof pillar width,and then analyzed the fault transmission, the width of fault waterproof pillar under different safety factor. These work laid the foundation for the safe mining of coal mines.
