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 rock formation borehole detector, static and dynamic observation of the surrounding rock of the roadway is carried out. The processing and analysis of the imaging results intuitively reflect the formation of surrounding rock and the development and distribution of fractures, and find out the location of fissure water outlet. Combined with the roadway support scheme, borehole detection was carried out for the surrounding rock of roadway in different periods. The distribution and development of fractures in different stations were analyzed. Not only the effect of roadway support was tested, but also the law of development and development of the fracture of surrounding rock was obtained.
