207运输顺槽过陷落柱技术应用分析

Application of Technology for 207 Transport Crossheading Passing Collapse Column

207运输顺槽在掘进过程中遇到一个较大的陷落柱。为了保证掘进的安全进行,需要采用合适的方式过陷落柱。根据实际情况,制定了绕巷过陷落柱的施工方案。重点介绍了在过陷落柱时采用的支护方式,包括临时支护方式和永久支护方式。按照设计方案,在一个月的时间安全通过了陷落柱。希望所述内容可以为煤矿巷道掘进过陷落柱提供一定的参考和借鉴。

207 transport crossheading encountered a large collapse column in the process of tunneling.In order to ensure the safety of the excavation,it is necessary to adopt a suitable way to pass the collapse column.According to the actual situation,the construction scheme of passing the collapse column around by skirting it was formulated.This paper mainly introduced the support modes used in passing the collapse column,including temporary support and permanent support.According to the design plan,the crossheading passed the collapse column safely in a month's time.It is hoped that the mentioned content can provide some reference for coal mine roadway passing collapse column.
