针对某铁矿二期工程采矿范围内的水文地质条件和矿井充水因素及以往报告中该铁矿二期工程采矿范围内的矿坑涌水量预测值进行了分析,基于该矿一期工程帷幕注浆的堵水率和解析法分别预测了该铁矿二期工程实施帷幕注浆工程以后的矿坑涌水量。综合预测结果为:二期帷幕工程以后的正常矿坑涌水量为20093 m3/d,二期帷幕工程以后最大矿坑涌水量为31212.7 m3/d。根据预测结果和矿山实际情况,提出了一些建议。
Based on the hydrogeological conditions and water filling factors within the mining scope of the second phase of an iron mine as well as the predictions of mine gushing water within the mining scope of the second phase of the iron mine reported in previous reports, The water plugging rate and analytic method respectively forecast the water inflow of pit after the curtain grouting project in the second phase project of the iron mine. The comprehensive prediction results are as follows: the normal pit water inflow after the second curtain project is 20093 m3 / d, and the largest pit water inflow after the second curtain project is 31212.7 m3 / d. According to the prediction results and the actual conditions of the mine, some suggestions are put forward.
