中文摘要:

从水文地质条件、充水情况等方面研究影响司家营铁矿Ⅲ采场地下水涌水量因素;在矿区水文地质条件的基础上,进行了矿区地下水均衡计算,通过矿区地下水影响因素的综合分析,计算出矿区地下水总补给量和总排泄量,得出两者的平衡关系;分别采用大井法及数值模拟法,对司家营铁矿Ⅲ采场露天转井下深部开采不同中段的地下水涌水量进行计算,并结合自然降水和考虑露天采场回填废石影响,系统预测了不同开采中段矿坑总涌水量。研究成果表明,矿区地下水呈负均衡状态,对矿区开采呈有利态势;矿坑系统涌水量综合预测结果与阶段性的实测资料较为一致,为司家营铁矿Ⅲ采场井下防排水及地质环境保护奠定了基础。

英文摘要:

It discusses the influence factors of water inflow of groundwater in the Ⅲ stope of the Sijiaying Iron Mine in terms of hydrogeological conditions, water-filling conditions, etc. The analysis of groundwater balance is carried out on the basis of the examination of the hydrogeological conditions. Through the comprehensive analysis of the influence factors of groundwater in the ore district, the total recharge and abstraction of groundwater are calculated, and the balance relation is obtained. Thus, the results of water inflow in different middle parts in the period from open-pit to underground mining in the Ⅲ stope of the Sijiaying iron mine are predicted by using the big-well method and the numerical simulation method. By considering the natural rainfall and backfilling waste rock in the open pit, the total water inflow in different middle parts of the mining pit is predicted. The research results show that the balance relation of groundwater in the ore district is in a negative equilibrium state, and this state is helpful in mining. The comprehensive prediction results of the systematic water inflow in the mining pit are basically consistent with the periodic measured results, and they lay a solid foundation for the underground waterproof and drainage and geological environmental protection in the Ⅲ stope of the Sijiaying iron mine.
