基于矿井生产分块段和分水平的三维地下水数值模拟

Numerical simulation of three-dimensional groundwater based on segmentation and sub-level of mine production

涌水量预测是矿井防治水工作中的重要内容,但矿井分多块段多水平开采时,一般方法无法准确预测矿井涌水量。本文以鹤岗矿区南山矿为例,结合矿井分块段分水平的采掘规划动态预测矿井涌水量,为矿井建立采区排水系统和制定各采区防治水措施提供依据。

The prediction of water inflow is an important part of the mining water prevention and control work. However,when the mine is divided into multiple mining sections, the general method cannot accurately predict the mine water inflow.Nanshan Mine in Hegang Mining Area was taken as an example, this paper combined the mining plan of the sub-section of the mine to dynamically predict the mine water inflow, and provided a basis for the mine to establish the drainage system of the mining area and formulate water prevention measures in each mining area.
