Research on the Drilling Matching Machines for Accumulation Body Anchoring at High-steep Slope

Abstract:

Because of high-steep slope, difficulties are often encountered, such as drilling rig relocation & erection and borehole completion in crushed bottom. Anchor drill was selected and improved in order to meet the requirements for the anchor cable construction in accumulation body at high-steep slope; and meanwhile eccentric drill with casing was developed and manufactured, hoping to solve the difficulties of anchoring borehole construction in accumulation body at high-steep slope, overcome low efficiency and high cost.
