宝鼎矿区浅部资源行将枯竭,深部开采已迫在眉睫,而预测深部涌水量成为其首要解决的问题。通过对矿区深部水文地质条件研究与矿井充水因素的分析,认为矿区各含水间水力联系差,同一含水层组的不同地段间的含水裂隙的连通性亦差;断层多为高角度压性逆断层,导水性差,富水性弱;矿区上部水平及下部水平的浅埋区的充水水源主要为大气降水和老窑水,而下部水平主要的充水水源为上覆水平的采空区积水和地下水。运用比拟法和地下水动力学对延深的第一接替水平四个区段的较大涌水量和一般涌水量进行了计算,经过比较,采用了比拟法的计算结果:矿井的一般涌水量为2860.88m3/d,据此提出了切实可行防治水措施,从而为矿井深部建设提供了水文地质依据。
The shallow resources in Baoding Mining Area will be exhausted and deep mining is imminent, and the prediction of deep water inflow becomes the primary problem to be solved. Through the analysis of deep hydrogeological conditions and mine water filling factors in the mining area, it is considered that the hydraulic connection among the water areas in the mining area is poor, and the connectivity of the water-bearing fractures in different sections of the same aquifer is also poor. Fault, poor water conductivity, weak water-rich; shallow water in the upper and lower mining areas mainly for atmospheric precipitation and old kiln water, while the lower level of the main source of water for the overlying water mined area Water and groundwater. By using comparative method and groundwater dynamics, the large gushing water amount and general gushing water amount in four sections of the first succeeding level of extension are calculated. By comparison, the calculation result of the comparative method is as follows: the general gushing water amount of the mine is 2860.88 m3 / d, thus put forward feasible measures to prevent and control water, thus providing a hydrogeological basis for deep mine construction.
