针对煤田矿井涌水量预测的复杂性,以山西平朔安家岭井工矿为例,在概化出矿区水文地质概念模型的基础上,建立了安家岭井工矿矿井涌水量预测的地下水三维非稳定流数值模拟模型,并结合矿井生产,按矿井掘进工作面进行了平水期和丰水期两个方案的涌水量预测,获得了各工作面不同时期地下水位分别疏干到4#煤底和9#煤底的矿井涌水量。该方法将矿井涌水量预测和矿井的水文地质结构及矿井生产进度紧密结合起来,具有较高的精度。
Aiming at the complexity of coal mine water inflow prediction, taking the Anjialing well and mine in Pingshuo, Shanxi as an example, based on the conceptual model of hydrogeology in the outburst mining area, three-dimensional groundwater unsteady flow Numerical simulation model and combined with mine production, according to mine heading face, the water inflow prediction of two schemes of flat water period and heavy water period was carried out. The groundwater level of each face was dredged to 4 # coal bottom and 9 # Coal mine water inflow. This method closely integrates the prediction of mine water inflow with the hydro-geological structure of mine and the progress of mine production, and has high precision.
