摘要
分析矿井涌水的影响因素、矿井开采过程中周边岩体的地压变化,得出开采深度影响涌水的机理.采用水文地质比拟法原理,结合2组实例统计数据,应用采深比拟法和SPSS软件函数拟合,得出开采深度对矿井涌水量的影响.从水文地质、地质构造、矿体赋存条件、开采方法、矿岩的物理力学性质、自然环境等方面分析影响矿井涌水的因素;结合海姆定律、开挖应力变化范围说明采深和地压变化的关系,得出采深影响涌水的机理.拟合结果表明:外部因素的不同如岩溶裂隙发育,采用多种工程类比法,选取其中最优的进行预测,具有优越性.
The mechanism of mining depth on the water gushing by analyzing the ground pressure change in the surrounding rock mass was studied. Function fitting between Mining depth simulation method and SPSS software based on hydrogeological analogy method leads to the effect of mining depth on the mine inflow.Factors affecting mine gushing, including hydrogeological conditions, geological structure, ore body conditions,mining methods, physical and mechanical properties of minerals and natural environment, are investigated.The relation between mining depth and ground pressure variation is also explained, based on Heim Law and excavation stress range.
