After the power supply system reduces the voltage of the high-voltage power from the mining area, the high-voltage power is scientifically and reasonably distributed to all large and small equipment on the fully mechanized mining face, so that all electromechanical equipment can be ensured to be operated safely; the hydraulic system is a power source of the hydraulic support of the fully mechanized mining face; the spraying system is a water supply pressure source of a spraying dust-settling system of the fully mechanized mining face.

The traditional equipment train comprises 35-45 carriages, the length of the train is about 200 meters, the track moving mode is adopted, and the pull-back winch counter-pulling traction moving mode is adopted in many cases. Two ends of the equipment train are respectively provided with a prop pulling winch, each winch is required to be provided with a root before the equipment train is moved, and a winch steel wire rope is connected to the root.

3. The use of the single-rail hanging pipeline hanging device greatly increases the length of the power supply and liquid supply pipeline of the fully mechanized coal mining face, increases the maintenance workload, has high maintenance and replacement difficulty, and has certain voltage drop on a power cable power supply line.

4. In order to reduce the influence on production, the train moving equipment can only be overhauled, and the time of overhauling is occupied.

5. The rail clamping device is adopted to fix the equipment train, so that the human factors are more, and the safety and reliability of the train are obviously reduced.

6. By adopting the monorail crane pipeline hanging device, the cost of installing the hanging anchor rod is increased, and the unsafe factor of falling objects is increased.

7. And the winch is adopted for opposite-pulling traction, so that multiple cautionary matters are increased, and unsafe factors are further increased.
