急倾斜岩溶充水类型矿井涌水量计算方法

The Water Inflow Quantity Calculative Method of Steep Pitch Mine of Karst Water Filled Type

通过孔集井田A组煤底板岩溶水水文地质及水动力条件的分析,建立了水文地质概念模型。并根据疏(放)水试验成果,对太灰Ⅰ组涌水量进行分区计算,建立了相应的比拟方程,对模型进行验证。结果表明:开采A组煤实际疏干水量与模型计算结果吻合程度较高。

A hydrology geology concept model is build up through analysis of Karst water hydrology geology and its hydrodynamic condition of a set coal floor in Kongji minefield. According to the dewatering test result, I set water inflow quantity of Taiyuan group limestone is calculated by sub area and analogous equation is established, and carry on verification to the model. The result express： The anastomotic degree of the practice dewatering quantity by mining A set coal and the model calculation result is higher.
