摘要
对矿山斜坡道设计的几个重要问题进行了阐述,采用了不同的支护方案对不同围岩支护,使用锚网喷并封底的联合支护技术对软岩进行支护。对长距离的独头掘进通风问题进行了研究。获取了不稳固岩石条件下斜坡道掘进的经验。
The article elaborates several problems regarding mine decline engineering, and provides different supporting plans for different host rock, especially the sealed and bolted mat supporting technology for unstable rock. In light of leading face of excavation, ventilation issued is specifically addressed. Finally the article concludes the experience of of decline excavation under unstable rock condition.
