基于锚杆强度深度优化的大断面巷道支护技术

Support Technology of Large Section Roadway Based on Optimization of Bolt Strength and Depth

煤矿开采事业的不断发展促使矿井开采深度日益增大,虽然煤矿开采效率与质量得到保障,但是也增大煤矿开采作业的安全隐患.需要借助对巷道支护技术科学优化,保障煤矿开采安全,控制巷道围岩稳定性.基于此,本文针对基于锚杆强度深度优化的大断面巷道支护技术进行探析.

With the continuous development of coal mining industry,the mining depth of coal mine is increasing day by day.Although the efficiency and quality of coal mining are guaranteed,the hidden danger of coal mining operation is also increased.It is necessary to control the stability of the surrounding rock of the roadway with the help of scientific optimization of the roadway support technology to ensure the safety of coal mining.Based on this,this paper analyzes the support technology of large section roadway based on the optimization of bolt strength and depth.
