煤矿联巷开口快速掘进技术与施工组织探究——以2306工作面底抽巷措施巷为例

Research of Speedy Drivage Technology and Construction Organization of Coal Mine Lane Opening——Through Taking Bottom Pumping Lane and Measure Lane of 2306 Working Face as an Example

针对地质构造简单、水文地质条件相对较简单且煤层瓦斯含量高的煤矿回采工作面,在回采工作面底抽巷措施巷等掘进与支护施工过程中,提出了新的联巷开口快速掘进技术、巷道支护设计及施工工艺,为煤矿联巷开口快速掘进、巷道稳定及矿井安全高效生产奠定了基础,对同类型地质条件的矿山巷道施工具有一定借鉴意义。

According to the coal mine stope face of simple geologic structure,relatively simple hydrogeological condition and high content of gas-bearing capacity of coal seam,in the process of tunneling and timbering construction of bottom pumping lane and measure lane of working face,the research proposes the new speedy drivage technology of lane opening,lane supporting design and construction technology to lay foundation for the speedy drivage of coal mine lane opening,lane stabilization,safe and efficient production of mine safety.This provides certain significance for mine workings construction under the same geological conditions.
