摘要
对矿井的具体掘进工作面进行研究,对高强度经济支护技术进行优化,即在一定的围岩和最小支护强度条件下,进行支护系统的局部优化,最终达到减少巷道支护强度、提高支护系统整体性和降本增效的目的。
Based on the specific working face of mine, economic and technical support of high strength was optimized, that is in certain rock and minimum support strength under the condition of local optimization of supporting system, and finally reduce the roadway support strength, improve the supporting system of the whole body, to achieve cost reduction and efficiency purpose.
