数值法和解析法在矿井涌水量预测中的应用分析

Application analysis of numerical method and analytical method in prediction of mine discharge in mine shaft

针对马城铁矿矿井水文地质条件、工程地质条件复杂及开采技术条件为复杂型复合问题矿床这一特点,在分析矿井地层资料以及以往的水文地质资料、查明矿区水文地质条件基础上,采用数值法和解析法对该矿井的涌水量进行了预测计算,所得结果可以作为矿井建井的设计依据。将2种方法的预测结果进行分析比较,综合考虑这2种方法的优缺点和矿井实际情况,认为数值法计算结果比较合理,研究结论可为其他类似矿井涌水量的预测提供借鉴。

The geological conditions and engineering conditions of Macheng iron ore are complex,and the mining method used in the ore is complex and combined. Based on the water inflow observation data and the stratum data of Macheng iron ore,the water inflow was calculated by the numerical method and analytic method. Two predicted results were similar and could be used as the design basis for iron ore construction. The corresponding application conditions for these two methods were given out after the analysis and the comparison,and it is considered that the result of numerical calculation is reasonable. It provides a reference for other mines to predict the water inflow.
