针对峰峰集团某矿S201巷道位于孤岛煤柱中以及向斜轴部的特殊地质条件,提出了等面弱结构双支护技术,详细介绍了其概念内涵、支护机理及布置方式,结合现场条件确定巷道支护参数并通过了现场实施。矿压监测结果表明,巷道支护效果良好,为类似高支承应力巷道的支护提供了借鉴。
In view of the special geological conditions of the laneway of S201 mine in Fengfeng Group located in isolated coal pillar and the special geological conditions of syncline axis, the double support technology of isostructural weak structure is proposed. The connotation, support mechanism and arrangement are introduced in detail. Conditions to determine the parameters of roadway support and passed the on-site implementation. The result of mine pressure monitoring shows that the effect of roadway support is good, which provides a reference for the support of similar high stress roadway.
