It can effectively support the roof in a timely manner and prevent roof accidents. It has high working resistance and good support effect, and can effectively control the roof, ensuring the safety and normal production of the coal face. Using an electro-hydraulic control system, it is simple and convenient to operate, has a high degree of automation, and can greatly reduce the labor intensity of workers and improve coal mining efficiency. It has complete safety protection devices, such as safety valves and hydraulic check valves, which can effectively prevent overloading and instability of the support, ensuring the life safety of coal miners.
