摘要
集贤矿区地质勘探报告中预测的矿井涌水量是250m3h/,但目前矿井实际涌水量达1700～2000m3h/,通过对开采前后水文地质资料的分析对比与研究认为,对矿井开采后地下水动力条件的变化缺乏足够认识,采用的矿井涌水量预测模型与实际情况不符是导致预测的矿井涌水量与实际涌水量相差很大的主要原因。
The predicted mine inflow in the ＂Jixian Mining Area Geological Exploration Report＂ is 250m^3/h, but the present actual mine inflow is as high as 1700-2000 m^3/h. Through analysis and contrast of hydrogeological data before and ＇after mining operation, has figured out that there is impercipient of changes of underground water dynamics ＇after the starting of mining operation. The main reason of the major difference between predicted and actual mine inflow is the mine inflow predicting model per se has lack of conformity with how matters stand.
