| 摘 要： | 开采受奥灰水威胁的煤层时,通常都把突水系数作为安全评价的依据,此方法存在一定局限性。采用室内小尺寸水力压裂试验测得煤层底板的阻水系数;用实测的阻水系数对兴隆庄煤矿首采区下组煤(16上煤、17煤)带压开采时奥灰水的突水危险性进行了评价。结果表明,该方法评价奥灰突水危险性直观、清晰、简洁,值得推广。

| Abstract: | The coefficient of water-invasion is usually used as judgment criterion when the coal seam suffered from Ordovician limestone water invasion.This paper adopts small-size indoor experiment of hydraulic fracturing to measure the coefficient of water-resisting of coal seam floor.The coefficient of water-resisting is used to evaluate the dangerousness of Ordovician limestone water invasion in the exploitation of lower coal seam(Coal16、Coal17),the first mining area,Xinglongzhuang Mine.Resultsindicated that this method is of feasibility for evaluating dangerousness of Ordovician limestone water invasion. |
