松软破碎矿体巷道掘进与支护技术

Technology of Roadway Excavation and Supporting in Loose and Cractured Ore Body

巷道掘进与支护是采矿工程的技术关键。本文以漓渚铁矿松软破碎矿体为例,较全面地介绍了控制爆破技术、掘支综合配套工艺技术等。

The roadway excavation and supporting are crucial techniques in mining engineering. The paper takes the loose and cractured ore body in Lizhu Iron Mine as example to describe in a all—round way the controlled blasting technique and combined excavation and supporting technology.
