摘要
通过应用TYGD10型岩层钻孔窥探仪,对五家沟矿5204工作面主运顺槽及辅运顺槽顶板窥探,通过不同地点实验结果分析,得出了顶煤变化和顶板岩性变化规律,可作为锚杆支护设计的依据,现场应用效果显著。
Through the application of TYGD 10 rock drilling detector, main transport crossheading and the roof of auxiliary transport crossheading in Wujiagou 5204 working face is dectected. According to the analysis of experimental results from different locations, change laws of the top coal and roof lithology are obtained, which can be taken as the basis for the design of the bolt support. Field application results are obvious.
