摘要
为了研究复杂地质环境下煤炭井工矿开采防治水工程三维非稳定流模拟计算的理论,以平朔矿区安家岭井工矿防治水工程为例,采用三维有限差分数值模拟理论,建立了平朔矿区安家岭井工矿防治水工程三维数值模型,在对模型进行识别、验证的基础上,按整个矿区疏干和分采区面疏干两种方案,模拟了多层含水层情况下各采区煤矿地下水位疏干到4#煤和9#煤所需的最小抽水量。
In order to study the theories of simulation calculation for three-dimensional unsteady flow of waterproof and water control project in underground coal mine, which is under complicated geological environment, in this paper the theory of three-dimensional finite difference numerical simulation was applied in waterproof and water control project of Anjialing underground coal mine of Pingshuo mining area, then three-dimensional numerical model was set up. Based on identification and verification of the model, the required value of minimum quantity of pumping water was obtained by simulation according to two schemes of whole mine dewatering and paneling dewatering respectively, when underground water level of each mining area was drained to No. 4 and No. 9 coal seams with multi-aquifers.
