Abstract The first positive-going 7665MZ series air-leg rock drill is not only used for drilling various rock holes and vertical bolt holes in the roof of the roadway, but also for stirring resin and installing anchor bolts. Based on the research and experiment, this paper discusses and puts forward the conditions of use necessary for the coal mine to use this machine to install the bolt.
