为了研究煤矿顶板透水机理,揭示顶板透水规律,以便为矿井开采、防治水技术措施提供设计依据,根据黄陵矿区长壁综放工作面开采技术条件和岩石力学性能等参数,建立力学模型,运用岩石破裂过程分析软件RFPA2D,对自开切眼至充分采动全过程覆岩随工作面推进时的变形、裂隙带发育、冒落情况进行了数值模拟,模拟过程中的透水量和实际检测到的透水量相吻合。
In order to study the pervious mechanism of coal roof and to reveal the law of pervious roof, in order to provide design basis for mining technology and water control measures, a mechanical model was established according to the technical conditions of mining and longwall mechanized top coal caving mining face in Huangling Mine. The rock burst process analysis software RFPA2D, which simulates the process of water breakthrough and actual detection of the deformation, fracture zone development and caving situation of the overburden strata along the working face during the process of fully openworking, The amount of water consistent.
