摘要
将围岩松动圈支护理论应用于实践 ,以实测围岩松动圈值为依据 ,并考虑动压对松动圈发展的影响 ,设计锚杆支护参数 ,将掘进巷道支护和回采超前维护用锚杆支护一次完成 ,取得了较好的技术经济效益。
This paper applies rock softcircle support theory to practice,takes rock softcircle numerical value as basis and think over moving pressuve influence to rock softcircle developing designs parameter of bolt support makes driving rockway support and actual mining lead upholding to finish once with bolt support it take good economic benefits of technology.
