【摘要】 综采放顶煤技术是当前我国煤炭工业实现高产高效的主要技术途径,但因推进速度快,对煤层开采有了更高的要求,如开采工作面涌水量不能太大,更不用说突发性涌水事故。因此应做好采前的水文地质勘察工作,查明富水区分布情况并预测开采涌水量大小。本文仅以兖州矿业集团公司兴隆庄煤矿1302工作面为例,分析预测综采放顶煤开采顶板涌水量。分析预测时采用了地下水动力学解析法和三维有限元数值模拟方法。更多还原

【Abstract】 Fully mechanized sublevel caving mining method has became main technique used in high-efficiencycoal industry in our country. Many new problems occur with fast mining progress, for example, water gushing yieldof working face isn t too much than that in traditional method, saying nothing of sudden flood. So hydrogeologicexploration should be done before mining. Distribution of ground-water and forecasted water gushing yield shouldbe ascertained. The paper deals with the study on analysis and forecasting of water gushing yield of bed top in fullymechanized sublevel caving mining from an example of 1302 working face in Xing Longzhuang Mine of YanzhouCoal Mining Group Ltd. Hydraulics analytic method 3-D finite element numerical simulation is adopted in analysisand forecasting.更多还原
