为解决超千米岩层低强度和高应力支护问题,通过地应力场实测获取基础数据,应用"快速高强、多结构、多元化支护、注浆加固及释压理论,使开挖支护后的巷道表面形成足够强的刚体,阻止巷道围岩松动破碎及变形引起的锚固力迅速衰减和丧失,通过巷道稳定性分析、信息化监控量测,实现巷道的支护控制,保证安全生产。
In order to solve the problem of low strength and high stress support for ultra-km rock formations, the basic data were obtained through the measurement of geo-stress field, and the theory of rapid high strength, multi-structure, diversified support, grouting reinforcement and pressure relief theory was adopted to make the excavation branch After the road surface protection to form strong enough rigid body to prevent the roadway surrounding rock loose broken and deformation caused by rapid decay and loss of anchorage strength through the roadway stability analysis and information monitoring measurements to achieve roadway support control to ensure safety in production .
