硬夹矸大采高工作面煤壁稳定性分析

摘要

At present, working face of large mining height is widely used in the mining area with advantages of high safety, strong production capacity and fast resource recovery. In this paper, the author analyzed the influence mechanism of hard dirt band of coal seam to working face of large mining height, and verified coal wall and palisades falls based on theoretical analysis and indoor experiment and field measurement.%目前，大采高工作面采矿工作以其安全性高、生产能力强、资源回升快等优点在矿区得到了广泛应用。笔者分析了煤层硬夹矸对大采高工作面煤壁稳定性的影响机制，并在理论分析基础上，结合室内试验、现场实测方法，对煤层硬夹矸片帮机理进行了验证。
