In addition, when the long-distance transition is carried out, the cable which is too long cannot be dragged, so frequent power connection is needed, enough wiring ports are reserved in the roadway, the construction and maintenance cost of the roadway is increased undoubtedly, and the operation safety of the cable cannot be guaranteed due to frequent cable disassembly. The track is laid in the mine tunnel with better partial conditions, the track transportation application is wide, the production rate is high, the transportation distance is not limited, the economy is good, the dispatching is flexible, the track transportation condition is utilized in partial mines, all parts of the drilling machine are transported in a transition mode through the track car, the track car is high, the hoisting difficulty of the drilling machine to the track car is high in a limited space, the danger is high, meanwhile, the tunnel height is limited, the height of the tunnel drilling machine is required to be reduced in the track transportation process, and therefore the drilling machine is required to be further disassembled for transportation, so that the workload of the transition transportation of the drilling machine is definitely increased. From the viewpoint of comprehensive transfer efficiency, the rail transportation efficiency is not fully exerted.
