摘要
针对综采工作面传统的沿空留巷围岩结构控制方案存在的操作过程繁琐、支护技术要求高、可靠性差的缺陷,提出了一种新的沿空留巷围岩结构控制技术。在榆树坡煤业的实际应用表明,该控制技术操作便捷,支护效率高,对围岩具有极好的控制效果,能够显著地降低顶板断裂时的冲击作用。
Aiming at the shortcomings of traditional gob-side retaining roadway surrounding rock structure control scheme in fully mechanized mining face,such as complicated operation process,high support technology requirements and poor reliability,a new gob-side retaining roadway surrounding rock structure control technology is proposed.The practical application in Yushupo Coal Industry shows that the control technology is easy to operate,has high support efficiency,has excellent control effect on surrounding rock,and can significantly reduce the impact of roof fracture.
