摘要: 针对坚硬石灰岩顶板的特点,采用理论分析、数值模拟等研究方法对坚硬石灰岩顶板条件下沿空留巷技术进行了研究。通过对巷旁充填沿空留巷方法与人工放顶卸压沿空留巷方法的可行进行分析,确定了巷旁采用强制放顶的沿空留巷方法,设计了支护方案;通过数值模拟研究,分析了巷旁人工放顶条件下沿空留巷围岩应力分布规律,得出了巷道围岩变形规律,论证了放顶卸压法沿空留巷的可行性;通过工业性试验,得到了石灰岩顶板条件下沿空留巷矿压显现规律。

Abstract: In view of the characteristic of the hard limestone roof, by using theoretical analysis, numerical simulation method, the technology of the gob side entry under the limestone roof is analyzed. Forced caving mothod on the gateside is identified, and the support parameter has designed. By the numerical simulation, the reasonable of the protection method is analyzed. Through the scene industrial experiment, Strata behavior of the gob side entry under the limestone roof condition has obtained.
