摘 要:针对当前煤炭资源节约开采,发展绿色开采的趋势,煤矿将大力推广无煤柱开采。同时,顶板治理水平直接影响矿井沿空留巷的效果,而恒阻锚索在矿井顶板管理方面具有广阔的推广应用前景。通过恒阻锚索在东河煤矿顶板管理方面的技术应用实例,论述了其科学合理性,同时消除了顶板管理安全隐患,起到节本提效的作用。In view of current coal resource conservation and green mining development,non-pillar mining will be vigorously promoted in coal mines.Constant resistance anchor cable has broad prospects for promotion and application in roof management which directly affects the effect of the gob-side entry retaining.This article discusses the scientific rationality of the constant resistance anchor cable in the roof management in Donghe Mine.The results show that this technology could eliminate the security risks of the roof management,which could save costs and improve efficiency.
