摘要
针对章村矿松散破碎围岩巷道支护问题日益突出,若采用不适当的支护措施,将会造成巷道围岩变形愈加剧烈,最终导致巷道变形破坏的问题。分析了章村矿-200井底车场的变形破坏特片,提出针对性耦合注浆技术方案。实际应用效果表明,该方案支护效果良好,有效提高了巷道支护结构强度,取得显著应用成效。
In view of the increasingly prominent support problem of the roadway with loose and broken surrounding rock in Zhangcun Mine,if inappropriate support measures are adopted,the deformation of the roadway surrounding rock will become more severe,and eventually lead to the problem of roadway deformation and destruction.This paper analyzes the deformation and damage characteristics of the Zhangcun Mine-200 shaft bottom parking lot,and puts forward the targeted coupling grouting technology scheme.The actual application results show that the support effect of this scheme is good,and the strength of roadway support structure is effectively improved,and remarkable application results are achieved.
