摘　　要：为掌握南翼开拓巷道围岩松动圈情况,揭示围岩活动规律,卧龙湖煤矿在南翼轨道巷、南翼回风巷、南翼轨道斜巷等3条主要开拓巷道,选择典型断面进行围岩松动圈的雷达跟踪观测.另外,为校准地质雷达的观测成果,在南翼轨道巷、南翼回风巷分别设置了窥视观测孔进行观测.地质雷达与窥镜测试相结合,可以互助验证、互为补充.本次雷达探测成果对分析破碎软岩巷道强烈变形的原因,制定控制巷道围岩变形的支护技术方案具有重要意义.In order to grasp the situation of surrounding rock looseness circle of the opening roadway in the south wing and reveal the law of surrounding rock activity,three main opening roadways in Wolonghu Coal Mineoal,i.e.the south wing track lane,the south wing return lane,and the south wing track inclined lane,are selected to carry out radar tracking observation of the surrounding rock looseness circle with typical sections.In addition,in order to calibrate the observation results of the geological radar,the south wing orbit lane and the south wing return air lane are respectively set up peep observation holes for observation.The combination of GPR and endoscopic testing can be mutually verified and complementary.The radar detection results are of great significance to analyze the causes of the strong deformation of the broken soft rock roadway and to formulate the supporting technical scheme to control the deformation of roadway surrounding rock.
