| 摘 要： | 针对我国煤炭资源开采现状，为解决煤炭开采与生态环保、水资源之间的矛盾和冲突，实现绿色开采的多赢目标，在系统阐述“煤—水”双资源矿井开采概念与内涵的基础上，通过理论分析、数值模拟等方法，对比分析垮落法和充填开采两种不同开采方式对上覆岩层运移规律的影响程度，提出了以绿色充填开采实现“煤—水”双资源矿井资源属性正效应的研究思路及方法。研究结果表明:充填开采控制顶板，上覆岩层不出现“三带”变化，仅出现“两带”，降低了覆岩破坏高度，阻断岩层的破断，起到了抑制水害发生的作用；充填步距、充填率、充填体强度与上覆岩层下沉值呈线性关系。相关研究成果对类似条件下的“煤—水”双资源矿井具有一定的借鉴意义。

| Abstract: | In view of the current situation of coal mining in China，in order to solve the contradiction and conflict between coal mining and ecological environmental protection，and achieve the win-win goal of coal mining green mining，this paper systematically expounded the concept and connotation of "coal-water" dual-resource mine exploitation，and compared the influence of caving method and filling mining on the migration law of overlying strata the scores by means of theoretical analysis and numerical simulation.The idea and method of realizing the positive effect of mine resource attributes by green filling mining were put forward and studied.The results showed that there is no "three zones" change in the roof of filling mining management，only "two zones" appear in the overlying strata，which reduces the failure height of overlying strata and prevents the breakage of the strata from occurring water hazards.The results have certain reference significance and application value for the coal water dual resources mine under similar conditions. |
