What are the components and characteristics of coal mining machines?
The coal cutter mainly consists of an electric motor, hydraulic transmission part, traction transmission part, cutting part, base frame, lifting oil cylinder, cable dragging device, etc.
Compared with similar types of units, the coal cutter has the following characteristics.
(1) The body length is short and narrow, with a wide range of adaptability;
(2) Major components are designed according to the power of a 250KW electric motor, with a large strength margin and high reliability. It can become a 250KW coal cutter by simply replacing the electric motor.
(3) The drum cutting torque is relatively large, capable of cutting hard coal;
(4) It adopts hydraulic stepless speed regulation. The gear-pin row type traction without chain operates smoothly and has a large traction force. The traction transmission part is set at both ends of the body. By using a dual traction mechanism, it not only reduces the pressure ratio of the transmission gear on the pin row, extending the service life of the pin row, but also greatly increases the overall traction force, with a maximum traction force of 350KN;
(5) The system is simple and reliable, with centralized control handles, making operation and maintenance convenient;
(6) The oil motor and brake are arranged on the traction transmission part near the old pond side, making it easy to replace underground, and the oil quality is not easily contaminated;
(7) It adopts an internal and external spray cooling system to improve the working environment and enhance the reliability of the coal cutter's operation.
(8) It uses a cable dragging device to protect cables and water pipes, reducing the labor intensity of workers;
(9) The power supply voltage has two types: 660V and 1140V, to meet the needs of different users.
(10) The electric control type of the coal cutter adopts power carrier wave control, which can reduce control core wires, eliminate multi-core cables, and complete various action functions, ensuring the safe and reliable operation of the coal cutter.

The coal mining techniques that are commonly used underground in coal mines.
The blasting mining process uses blasting methods to extract coal mines. In practical applications, the selection of blast holes is crucial. If the design is improper, the blasting effect will be affected. In mild cases, there may be blasting deviations, impacting the extraction volume; in severe cases, it can cause losses to life and property. A large amount of dust is generated after blasting, and the mining area needs to be managed post-blasting.
