地质构造带巷道动态化施工方法的应用

Application of dynamics construction methods of roadway in geology structure zone

断层带、淋水带及破碎带是巷道支护施工中难度很大、容易出现事故的地段。本文结合刘桥一矿Ⅱ66回风下山过DF20断层施工的实例,采用基本地质条件监测、施工监测监控等方法,通过数据分析处理,将处理结果动态反馈于施工过程中,此即巷道动态化施工。该方法在巷道穿越地质构造带施工指导中取得了令人满意的结果。

The fault, tricking and crush zone are the very difficult and catastrophic sector of the roadway during the course of support. Combined with 1166 return air down through the construction of fault DF20 in Liuqiao No.1 coal mine, the monitoring of the basic geological conditions, construction monitoring and controlling construction were used. Through data analysis and processing,the results are dynamically fed back to the construction. These processes are called dynamics construction methods of roadway,which is applied to the roadway through fault DF20 and gives a satisfying effect.
