摘要

摘要: 矿坑涌水是矿山地下开采面临的首要问题，合理的涌水量预测方法是目前国内外研究的热点和难点所在。本文以湖南省道县铁锰矿Ⅱ矿体-50 m开采水平为例，利用有限差分数值方法对矿坑开采的涌水量进行模拟与分析。计算结果表明，涌水量主要来自于车子江的补给，但东部、南部、北部及降雨的补给量所占比例增大，说明Ⅱ矿体涌水量来源较广泛。综合分析，数值法所计算出的不同季节、不同雨强特征的涌水量，更符合矿区实际条件，模拟结果可以作为矿区开采设计的依据。

Abstract: Water gushing of mine is the most important issue in mining, and reasonable predicting method for gushing water is a hot and difficult problem in research circle at present. Ferromanganese mine Ⅱ in Daoxian, Hunan is taken as the example. The water gushing of mine is simulated by means of finite-difference methods. The simulation results shows that the gushing water mainly comes from the Chezijiang river but the water come from rainfall, the east, south and north boundary increase, which proving the gushing water is recharged widely. On the other hand, the lithology and geological structure as well as groundwater characteristics are investigated, the boundary conditions are determined, and the finite difference numerical methods are used to simulate the groundwater. The results show that, the numerical simulation can be used to forecast water gushing of mine in different conditions and different mining level as well as complex hydrogeologic conditions. In one word, the simulation results can be used as the basis for the design of mining.
