正利煤业14-1201工作面运输巷差异性控制技术研究

Study on Difference Control Technology of Transportation Roadway in the 14-1201 Working Face of Zhengli Coal Industry

煤矿巷道围岩环境复杂多变,单一的控制技术不能实现巷道整体区域的稳定控制。以正利煤业14-1201工作面运输巷揭露多条断裂构造为工程背景,提出了巷道区域性差异控制、及时强主动控制原则、高强度护表和区域性表面喷层硬化原则等巷道差异性控制思路。巷道差异性控制技术的应用,实现了试验巷道的稳定控制。

The surrounding rock environment of coal mine roadway is complex and changeable,and the single control technology can not realize the stability control of the whole area of the roadway.Based on the engineering background of several fault structures exposed in the 14-1201 working face transportation roadway of Zhengli Coal Industry,this paper puts forward some ideas of roadway difference control,such as regional difference control,timely strong active control principle,high strength surface protection and regional surface spray hardening principle.The application of roadway difference control technology realizes the stability control of test roadway.
