摘要
焦家断裂带金矿密集,相邻矿山开采相互干扰明显,单一矿坑的涌水量研究工作已经不能满足矿山生产需求。通过建立多矿山联合开采的焦家控矿构造带地下水流数值模型,模拟预测干扰开采条件下不同开采中段的矿坑涌水量及随时间的变化规律,为矿山开采制定防治水方案提供依据。模型中采用barrier障碍边界模拟控矿构造阻水带对地下水水平流的阻碍作用,在传统水位及观测孔拟合的基础上,进行矿坑涌水量拟合校正,进一步提高模型模拟精度。
The gold deposits in Jiaojia fault zone are dense,and the mining of adjacent mines interferes with each other obviously.The research work of water inrush from a single mine can no longer meet the needs of mine production.By establishing a numerical model of groundwater flow in Jiaojia ore-controlling structural zone of multi-mine joint mining,the water inflow of pits in different mining sections under disturbed mining conditions and its variation with time are simulated and predicted.It provides the basis for the formulation of water prevention and control scheme in mining.In the model,the barrier boundary is used to simulate the hindrance of the ore-controlling structural water blocking zone to the horizontal flow of groundwater.On the basis of the traditional water level and observation hole fitting,the mine water inflow is fitted and corrected,and the simulation accuracy of the model is further improved.
