| 摘 要： | 为了确保工作面在综放开采条件下安全生产,研究了采动过程中因顶板冒落、放顶垮落造成的顶板透水的灾害机理.结合具体工程地质条件,利用固-液耦合相似材料模拟方法对首采工作面综放开采过程进行了研究,分析了裂隙带与冒落带导水通道分布特征,总结了含水层潜水渗流规律.模拟结果表明,当工作面推进到300 m左右时覆岩主关键层断裂,裂隙带发展高度到达含水层,为顶板透水提供了可能的通道.在此基础上,分析了采动岩体的周期破断与裂隙发展过程,划分了顶板透水危险区域,其结论可为大佛寺煤矿顶板透水预测及防治提供依据.

| Abstract: | In order to ensure the safety production under the condition of fully-mechanized caving in Dafoshi coal mine of Binchang mining area,we studied the mechanism of roof water inrush resulted from roof fall and simulated the mining process of the first coal mining face using the solid-liquid coupling material.In addition,we also analyzed the distribution of water conductors in the roof falling zone and summarized seepage flow rule of unconfined aquifer.The simulation result shows that when the working face is a... |
