摘要
利用TYGD10型岩层钻孔探测仪,对巷道围岩进行静态和动态观测。对摄像结果进行处理分析,直观地反映了巷道围岩构成以及裂隙发育和分布情况,并找出了巷道顶板裂隙水出水位置。结合巷道支护方案,对不同时期掘进巷道围岩进行钻孔探测,分析不同测站裂隙分布及发育情况,不仅对巷道支护效果进行了检测,同时得出了巷道围岩裂隙发展发育规律。
Using TYGD10 type rock drilling detector observes the roadway. The roadway constitution is directly reflected and water outlet location is identified by analysis of the camera results. Combing roadway programs for different periods of driving roadway drilling detect, different stations fracture distribution and development of the situation is analysed. The result not only detectes the roadway effects, but also draws the law of roadway crack growth and development.
