Application of Directional Kilometer Drilling Rig to Long-distance Detection of Small kiln Goaf and Geological Structure
Qingwa Coal Industry Co.,Ltd.,Jinneng Holding Equipment Manufacturing Group is a resource-integrated mine.Due to the long mining time,the small kiln is seriously damaged.In order to detect the scope of the goaf and the area affected by the geological structure,a scheme of using the kilometer drilling rig to detect the boundary of the goaf and the influence of the fault is proposed.On the premise of not affecting the excavation of the return air roadway,the kilometer drilling rig is used to detect the goaf and fault range around the roadway,which ensures the safe and normal operation of the working face and verifies the feasibility of the scheme.
