摘要
离壁支护是根据能量支护原理而研究开发的,是软岩巷道释放能量的一种新型支护形式。本文较详细的分析了软岩巷道支护时的力学性能和变形特征,并在此基础上结合能量支护理论分析了围岩和支护的相互作用,总结了离壁支护时围岩能量释放规律。珲春矿区的成功试用证明离壁支护合理可行,值得推广应用。
Supporting without back fill is a new support form to release energy in soft roadway which is researched and developed according to energy supporting principle.The paper analyzes mechanical properties and deformation characteristics of soft rock roadway supporting,analyzes the interaction of surrounding rock and supporting combining with energy supporting theory and summarizes surrounding rock energy release regulation of supporting without back fill.The successful probation in Huichun Colliery proves supporting without back fill is reasonable and feasible and should be widely applied.
