摘要
基于阳煤二矿龙门2号回风立井井筒现状和问题,针对井壁支护设计了对井筒重新浇筑混凝土支护、对破损地段重新喷浆支护两种方案,通过分析及技术经济比较,确定选择方案一。
Based on the present situation and problems of Longm en No.2 return air shaft in No.2 coal mine of Yangquan Coal Industry Group Co., Ltd., two schemes of re-pouring concrete support and re-shotcreting support in damaged areas are designed for shaft lining support. Through analysis and technical and economic comparison, the first scheme is determined.
