摘要
黄屯硫铁矿西部的金铜矿区属于新增资源,为查明西部金铜矿体的开采条件,在对矿区水文地质边界条件进行综合分析的基础上,建立矿区水文地质概念模型,运用比拟法与解析法两种计算方法分别对矿区矿坑涌水量进行了预测,结果表明:两种预测方法得出的结果基本相近。从安全因素考虑,建议将比拟法预测的-340 m中段正常涌水量1 001.5 m3/h(24 036.4 m3/d)和最大涌水量1 101.5 m3/h(26 436.4 m3/d)、-460 m中段正常涌水量1 354.9 m3/h(32 517.6 m3/d)和最大涌水量1 454.9 m3/h(34 917.6 m3/d)作为矿井防排水系统及相关设计的依据。最后根据预测结果,对矿井防排水系统及相关设计提出了合理建议。
Huang Tun gold copper mine areas belong to the new in the west of the pyrite resources,to find out the gold copper ore body mining conditions in the west,the mining area in hydrogeological boundary conditions on the basis of comprehensive analysis,establishing mining hydrogeological conceptual model,two calculation methods using the analogy method and the analytic method of mining area with a prediction of the mine water inflow,the results showed that: The results of the two forecasting methods are basically similar. For safety reasons,It is suggested that the normal water inflow in the middle section of-340 m is 1 001. 5 m3/h( 24 036. 4 m3/d),the maximum water inflow is 1 101. 5 m3/h( 26 436. 4 m3/d),the normal water inflow in the middle section of-460 m is 1 354. 9 m3/h( 32 517. 6 m3/d) and the maximum water inflow is 1 454. 9 m3/h( 34 917. 6 m3/d) as the basis of mine drainage system and related design. Finally,according to the prediction results,reasonable suggestions are put forward for mine drainage system and related design.
