岩石巷道的修复技术

Repair Technique of Rock Roadway

通过对许疃煤矿82下轨道下山二中车场贯通点(牛鼻子位置)上下约200 m地方的巷道修复问题进行研究,提出了在不同地点根据实际情况采用不同的联合支护方案。经过实践证明,该套修复技术,既恢复了巷道的原有功能,又有效地控制了围岩再次变形,为巷道的后期安全使用提供了有力的技术保障,具有推广应用价值。

By the research on the roadway repair at 200 meters from up and down connecting point（location on Niubizi） of the second middle station of 82 down side track in Xutuan Coal Mine,puts forward the different combined support plan in accordance with the actual situation at various locations.The repair technique of rock roadway not only can restore the original function of the roadway,but also control the second surrounding rock deformation effectively and provide a strong technical support for the latter safe use of the roadway, all of these have been proved by practise and have promotion and application value.
