深部矿井水地下调蓄系统研究

Study on underground regulation system of deep mine water

针对蒙陕地区深部矿井涌水量大、污水比例高、资源化利用率低等问题,研究利用采空区建设地下调蓄系统以稳定矿井涌水量、净化污水、降低水处理压力、提高矿井水利用率。根据煤层埋藏和开采条件,从调蓄系统建设条件和选址原则、容水量计算、水质保障、隔离工程建设条件、强矿压影响、安全性保障、经济和环境效益等角度,对矿井水地下储存、净化与调蓄进行了可行性研究。利用呼吉尔特矿区门克庆煤矿采空区建设形成矿井水调蓄系统示范工程,取得了良好的经济与环境效益。

Aiming at the large water inflow,high proportion of sewage and low utilization rate of resource in the bordering area of Inner Mongolia and Shanxi,it’s proposed to establish groundwater regulation and storage system to stabilize the water inflow,purify sewage,reduce water treatment pressure and improve water utilization rate of mine. According to the conditions of coal seam burial and mining,the feasibility study on underground storage,purification and regulation of mine water is carried out from construction conditions and location principles of the storage system,water storage capacity calculation,water quality guarantee,isolation engineering construction conditions,strong mine pressure impact,safety guarantee,economic and environmental benefits. Based on the feasibility study,the demonstration project of mine water regulation and storage system is formed using the goaf in Menkeqing Coal Mine in Hugilt mining area,and good economic and environmental benefits have been obtained.
