    • Abstract
  • In order to improve the construction efficiency of anchor bolting in coal mine roadway heading face, a compact size and well-adapted bolting machine on anchor excavator machine was developed, which can realize multi-angle drilling construction, and has the advantages of fast angle adjusting speed and high drilling efficiency. Three key parts including feeding mechanism, gyrator, and the hydraulic system are studied. The test shows that the drilling rig is designed reasonably and can meet the requirements of fast construction of bolt support of anchor excavator machine.
