以某萤石矿为例,在分析矿井水文地质特征的基础上,指出矿井的主要充水因素,并采用“大井法”和集水廊道法预测了矿区首开区的涌水量,各开采中段的预测结果分别为73.4、260.6、306.6、326.7、169.1 m3/d,为地下水疏排工程设计提供了设计依据。
Taking a fluorite ore as an example, based on the analysis of the hydrogeological characteristics of the mine, the main water filling factors of the mine are pointed out and the water inflow of the open area of the mining area is forecasted by using the “Big Well Method” and the catchment corridor method The predicted results in the middle section of mining are respectively 73.4, 260.6, 306.6, 326.7 and 169.1 m3 / d, which provide the design basis for the design of groundwater drainage engineering.
