Green Pioneer Meritorious Achievement| Sany pure water hydraulic support helps the green mining of Shenda Daqiaogou Coal Mine in Xinzhou, Shanxi

In September 2022, 141Sany refilled with pure waterHydraulic supportIt was put into use in the Shenda Daqiaogou Coal Mine in Xinzhou, Shanxi Province, and has been in operation for half a year.

For ecological and environmental protection, the solution of groundwater resource pollution is the top priority.Sany heavy water hydraulic supportThrough the pure water preparation device and the pure water high-pressure pump, the mine water is converted into pure water for use, which completely replaces the traditional emulsion and realizes zero pollution of groundwater resources.For the Daqiaogou Coal Mine in the Yellow River Basin,It not only reduces the ecological impact of coal mining, but also reduces the cost of coal mining, reduces the loss rate of parts, prolongs the service life of hydraulics, improves production efficiency, and realizes green, environmentally friendly, intelligent and efficient coal mining.

Since it was put into operation for half a year, this set of pure water support has helped the fully mechanized mining face of the 100101 to successfully complete the mining work, with a cumulative footage of 800 meters and more than 500,000 tons of coal. The Sany electro-hydraulic control system can monitor the real-time status of the hydraulic support and realize automatic control, which greatly reduces the labor intensity of workers, saves operation and maintenance costs, and makes mining more intelligent with simple operation.

Since its official launch in 2018, the pure water hydraulic support has been successfully used in Shendong Jinjie Coal Mine, Shendong Halagou Coal Mine, Shanxi Hualu Yangpoquan Coal Mine, Qinglong Sanbao Coal Mine and other coal mines, and its economical and efficient use performance has been widely recognized by customers.

       Sany heavy water hydraulic supportReplace the traditional emulsion with pure water medium, realize zero pollution of underground water resources, help coal mines achieve green and efficient mining, and now apply for 35 patents, including 16 invention patents, and won the second prize of scientific and technological progress of China Coal Industry Association.

Four core strengths

● Green and environmental protection

Through the perfect pure water preparation process and equipment, the emulsion is completely replaced with pure water to solve the problem of emulsion pollution.

● Clean and efficient

Closed liquid supply and return system + complete set of anti-corrosion technology for parts and components provide an excellent working environment for hydraulic parts and efficient coal mining.

● Economical and reliable

The use of pure water self-lubricating sealing technology reduces the failure rate of the hydraulic system by more than 20% and greatly reduces the cost of maintenance and replacement parts.

● Intelligent control

Real-time information monitoring and automatic control of water production devices, pumping stations and hydraulic supports are realized, and intelligent mining is carried out with less manpower.
