摘要
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。
This paper analyzes the hydro - geological conditions, water filling factors and the predicted mine water inflow values given in the past reports within the mining area in the second phase mining of some iron mine. Based on the water shutoff rate of curtain grouting in the first phase mining and analytic method, the mine water inflow in the second phase mining after imple- menting curtain grouting is predicted. The comprehensive prediction result is that the normal mine water inflow is 20093 m^3/d, maximum mine water inflow is 31212. 7 m^3/d in the second phase mining of the iron mine after curtain grouting. Finally, according to the predicted results and actual conditions of the mine, some suggestions are put forward.
