技改矿井涌水量计算中的问题探讨

Issues in Calculation of Water Inflow in Technical Transformation Coal Mines

针对技改煤矿防治水难的问题,尤其是对于多次多级改造升级的煤矿,准确计算矿井涌水量显得尤为重要。煤矿开采后水文地质条件一直发生着变化,含水层水文地质参数也在发生变化,因此计算矿井涌水量需要探讨一些关键问题。对西北一技改矿井涌水量计算的关键问题进行探讨,分析了矿井充水因素,分不同水平计算了矿井涌水量,探讨了水文地质概念模型的概化、水文地质参数的确定和涌水量计算结果的时空特性在计算过程中的重要性,以期对技改矿井防治水工作起到积极作用。

In view of the difficult water disaster prevention in technical transformation coal mines,especially in the coal mines rebuilt and upgraded many times,it is very important to calculate the mine water inflow accurately.The hydrogeological conditions have been changing after coal mining,and the hydrogeological parameters of aquifer are also changing,so some key problems need to be discussed in calculating the mine water inflow.The key problems in the calculation of water inflow in a technical transformation coal mine in northwest China were discussed,the factors of water filling in the mine was analyzed,the water inflow at different levels was calculated,and the importance of the generalization of hydrogeological conceptual model,determination of hydrogeological parameters and the spatial and temporal characteristics of calculation results of water inflow in calculation process were discussed,in order to play a positive role in prevention and control of water inflow in technical transformation coal mines.
