| 摘 要： | 为了减小开采对地下水资源的影响和破坏，根据开采引起导水裂隙带的形成机理，结合条带开采导致矿山压力较小，对上覆岩层的破坏较轻等优点，提出了宽条带跳采的采煤方法。通过数值模拟，分析了宽条带跳采和全部冒落法开采引起的降水漏斗的影响范围。结果表明：采用不同的开采方法对地下水资源的影响和破坏不同，采用宽条带跳采引起的降水漏斗的影响半径较小，对地下水的赋存、运移条件破坏较轻，为减小采动对地下水资源的破坏和环境恶化提供了一种有效的技术途径。

| Abstract: | To reduce the effect and destruction of mining on ground water,based on the mechanism of cranny strip brought about by excavation,and combined with the merit that strip-mining brings about less mine pressure and destruction to the terrane above coal seam,the mining method of wide strip skip-mining is put forward.The range of precipitation funnel arising from wide strip skip-mining and full-pillar mining is analyzed through numerical simulation.The result of study indicates that different mining methods have different effect on ground water,and the radius of precipitation funnel brought about by wide strip skip-mining is less,likewise the mining method bring about less damage on ground water.An effective technical solution is supplied for diminishing the effect on ground water and environment deterioration as a result of mining. |
