依据井巷喷射混凝土支护后期抗压强度低及回弹率高,致使人、财、物浪费严重的现状,提出改进和加强工艺流程管理等措施、办法,使井巷喷射混凝土支护达到科学管理和合理组织,以期实现提高井巷喷射混凝土支护的一次喷层厚度,且降低回弹、提高经济效益的目的。
Based on the low compressive strength and high rebound rate of shotcrete in the late stage, the present situation of serious waste of human, financial and material resources is put forward, and measures such as improvement and strengthening of process flow management are put forward to make the shotcrete support in the roadway reach the science Management and reasonable organization, in order to achieve the goal to improve the shotcrete shotcrete supporting the thickness of a spray layer, and reduce the rebound and improve economic efficiency.
