摘要
分析了在复杂的地质条件下 ,采用传统的架棚支护在扩掘大断面轻放切眼中出现的问题 ,给轻放工作面衔接带来的影响。结合围岩应力理论和现场实际情况 ,提出了改进扩掘轻放大断面切眼支护技术方案 ,阐述了首次采用单体液压支柱作为掘进承载支护的应用实践和取得的良好效果。
This paper analyze the problems of expanding mining caving lightly set-up room with traditional shield support,it took the influence to join caving lightly workface.It improves set-up room support technology in expanding mining caving lightly druwing section with surrounding rock force theory and practical condition in scene.It expounds applied practice of mining bearing support with hydraulic supported by individual props and gains a good result.
