The hydraulic two-arm bolting jumbo for coal mines is a new type of roadway support mechanical equipment. The machine is used in conjunction with the roadheader and the drilling unit to quickly complete the support work, achieve operational balance, and improve mechanization. Mainly used for coal rock and semi-coal rock roadway working face support operations. It can simultaneously realize the support of roadway top and side bars with bolts and cables. It also has the functions of drilling blast holes and detecting holes (water control, gas detection) in the coal seam.
