本溪思山岭铁矿矿排水涌水量预测研究

The Prediction Research of Si Shanling Iron Ore Mine Drainage Water Inflow in Benxi

为提高对矿排水水量预测的准确性,本文以拟建本溪思山岭铁矿为例,利用“大井”法、水平巷道法以及均衡法三种不同的计算方法对该矿山涌水量进行了预测,三者计算的矿山涌水量分别为3 123.04 m3/d、3 000.5-6 624 m3/d、3 096.77-3 211.65 m3/d。为安全起见,本次涌水量预测结果选取3000.5-6 624 m3/d。采用多种方法可以给出较为合理的涌水量范围,对矿山涌水量提供技术依据,为水行政管理部门审批取水许可提供参考。

In order to improve the accuracy of the prediction for mine drainage water, based on the proposed Benxi mountain iron mine as an example, using the method of ＂big well＂, drift method and equilibrium method to calculate the mine water inflow, three calculation of mine water inflow were 3123.04 m3 / d, 3000.5 m3 / d- 6624 m3 / d, 3096.77- 3211.65 m3 / d. To be on the safe side, the prediction of water inflow, 3000.5-6624 m3 / d. Water using a variety of methods can give reasonable scope and to provide technical basis for mine water inflow, provide a reference for water for examination and approval of the administrative department for water license.
