The invention discloses a
recovery method for a mine coalside anchor rod. The
recovery method comprises the following steps of orderly detaching and recovering coalside supporting components such as a coalside resin
metal anchor rod tray, a nut, a ladder beam and a net, and then extracting the coalside resin
metal anchor rod out by a wet coalside resin
metal anchor rod
recovery drilling tool. Three-toothed
diamond compacts are welded to a
coring drill bit of the wet coalside resin metal anchor rod recovery drilling tool, so problems of small
cutting output, slow propelling speed, poor rock-refuse breaking effect, inadequate power and great demand for labors of a common
alloy sheet
coring drill bit can be solved; with proper inner
diameter, wall thickness, numbers and length of the
coring drill bit, problems of irrational coring drilling rod inner
diameter design, coalside anchor rod interference, coalside resin metal anchor rod break due to extraction and multi-stage coring drilling rod use can be solved; and the
recovery method for a mine coalside anchor rod is advantaged by
safe operation, fast propelling speed, great rock-refuse breaking effect and high recovery
utilization rate.
