断裂构造往往是矿区的富水带和导水通道,在断裂构造发育区进行矿坑涌水量预测时,对断裂带的认识和研究程度会对涌水量预测的精度产生直接影响。该文以马城铁矿为研究对象,重点对工作区内构造断裂带的发育情况进行分析研究,通过建立三维地下水流数值模拟模型,采用抽水试验动态资料对模型进行识别,准确地预测了矿坑涌水量,为矿山开采提供了依据。
The fault structure is often the water-rich zone and the aqueduct channel in the mining area. When predicting the mine gushing water volume in the fault tectonic development zone, the understanding and research level of the fault zone will have a direct impact on the prediction precision of the gushing water. This paper takes MaCheng Iron Mine as the research object, focuses on the analysis of the development of the tectonic fault zone in the work area. By establishing the numerical simulation model of the three-dimensional groundwater flow and using the dynamic data of the pumping test to identify the model and accurately predicting the pit Water inflow, provided the basis for mining.
