多功能巷道修复机在工作面顺槽维修中的应用

Application of multifunctional roadway repair machine in maintenance of working face

阳煤一矿综放工作面巷道变形量大,采用传统的人工卧底、扩帮方式效率低,并且存在一定的安全隐患。以该矿8304工作面为例,现场调研了巷道的变形特征,分析了巷道的变形原因,为实现安全高效生产,采用巷道修复机进行巷道维修。通过对比常用的设备配套方案,确定采用WPZ-55/15/1000L型巷道修复机和胶带输送机组合的方式。在8304运输巷的应用表明,WPZ-55/15/1000L型巷道修复机是一种理想的巷道维修装备,工人劳动强度低、速度快、工效高,经济和社会效益显著。

The deformation of fully mechanized caving face roadway in Yangmei No.1 Coal Mine is large,and the traditional methods of artificial undercover and side expansion are inefficient,and there are some security risks.Taking the 8304 working face of the mine as an example,the deformation characteristics of the roadway were investigated on site,and the causes of the deformation of the roadway were analyzed.In order to achieve safe and efficient production,roadway repair machine is used for roadway maintenance.By comparing the commonly used equipment matching schemes,the combination of WPZ-55/15/1000L roadway repair machine and belt conveyor is determined.The application in 8304 transport roadway shows that WPZ-55/15/1000L tunnel repairing machine is an ideal tunnel repairing equipment with low labor intensity,high speed,high efficiency and remarkable economic and social benefits.
