Abstract: In recent years, with the adjustment of the national coal industry, the major mining bureaus are trying to improve the tunneling speed of the roadway, so they put forward higher requirements for the supporting equipment after the rapid tunneling of the coal roadway. According to different roadway driving modes, various types of bolt support equipment are developed successively. According to different geological conditions, two arm bolt drill with supporting roadheader, four arm bolt drill with supporting continuous mining machine and bolt transfer unit with supporting bolt driving unit are developed successively. Each of the three matching modes has its own advantages, but they can not be replaced by each other. Therefore, it is necessary to select the matching mode according to specific geological conditions.The way of driving.
