Problems solved by technology
Each fully mechanized mining face generally has hundreds of hydraulic support supports, and each support has its own independent hydraulic system. The hydraulic system includes hydraulic cylinders and hydraulic control systems. The hydraulic control system is divided into hydraulic valves and hydraulic supports. Composed of electro-hydraulic control devices, the early hydraulic control system only had a single hydraulic valve control component, which is commonly known as manual control. Personal safety is not guaranteed, and the production efficiency of underground coal mining is low
Since the 1990s, the hydraulic support electro-hydraulic control systems used by my country's coal mining enterprises are mainly from German DBT and American JOY companies. The high cost and difficult operation of the man-machine interface have increased the maintenance costs of coal mining enterprises.
