官地矿12609工作面运输顺槽支护技术研究

Study on Supporting Technology of Transportation Crossheading in 12609 Working Face of Guandi Coal Mine

以官地矿12609工作面运输顺槽为研究对象,对实际工程地质条件进行了分析,通过理论计算对锚杆长度、直径、间排距和锚索间距等主要技术参数进行分析,在此基础上结合以往的开采实践和支护经验,确定了合理的巷道支护方案。实践表明,巷道支护方案合理,巷道围岩得到了有效控制,可以满足工作面安全开采要求。

Taking transportation crossheading in 12609 working face of Guandi Coal Mine as the research object,this paper analyzed the actual engineering geological conditions,and analyzed the main technical parameters such as the length,diameter,separation distance and row spacing of anchor rod and separation distance of anchor cable through theoretical calculation,based on which,it determined the reasonable roadway support scheme combined with the previous mining practice and support experience.The practice shows that the roadway support scheme is reasonable,and the surrounding rock of the roadway has been effectively controlled,which can meet the requirements of safe mining.
