| 摘 要： | 提出了在控制采场顶底板水运移中隔水关键层的概念，建立了复合隔水关键层的基本力学模型，进而对具有5层岩层组成的复合隔水关键层进行了相关的强度和刚度分析，给出了不同组合的阻隔水能力判定. 从岩层运动与水体运移的视角提出了保水开采的矿压控制思路，为开发水资源保护性的煤矿绿色开采技术提供了相关的技术途径.

| Abstract: | The concept of the water-resisting key strata was proposed in controlling the roof and floor water movement in working face,and the mechanics model of the water-resisting compound key strata was established to analyze the strength and stiffness of the water-resisting compound key strata,which was composed of five rock seams.A sufficient condition was obtained for the water resistance capability of different rock seams combinations.The ground control thought of the water-preserved mining was brought forward from the visual angle of rock strata motion and water movement,which provides an effective technique approach to develop the green mining technology,which is benefit to the water resource protection. |
