Application of Pre-Mixed Abrasive Water Jet to Quit Anchor Underground

In coal production, those supporting anchor generally remain in the rock , at the endof the mine mining .We need to recover the anchors to maximize savings and reducing consumption , and accelerate the working face roof caving in roadway . The paper through the analysis of the disadvantages of traditional anchor back , put forward the application of pre-mixed abrasive water jet technology to the cutting of anchor rod and anchor rope . The experiments show that the technology not only meets the requirements of underground safe production, but has good cutting effect , high efficiency , saving a lot of manpower and time.
