Central media special focus! Sany Heavy Pure Water Hydraulic Support leads the "zero pollution" revolution of groundwater in coal mines

After years of meticulous management, the ecological protection of the Yellow River Basin has made significant progress, the water is cleaner and the surroundings are greener. Behind these changes, the protection of groundwater security is also an important part of the construction of ecological civilization. At 800 meters underground, the protection and management of mine water and the green transformation of the coal industry are also eye-catching, and the practice of governance and mine water protection in the Yellow River Basin is also eye-catching. Many coal mines actively practice the concept of environmental protection, and the central media special report focuses on Sany Heavy Pure WaterHydraulic supportHow to use the power of science and technology to achieve zero pollution of groundwater.

The reporter's on-site visit:Pure water replaces emulsion and cures the source of underground pollution

At a depth of 800 meters in a coal mine in Shanxi Province, the reporter experienced the operation scene of pure water hydraulic support. Different from the traditional emulsion stent, Sany pure water stent completely replaces the emulsion with a high-purity water medium, which completely solves the industry problem of emulsion infiltration and pollution of groundwater.

Wei Dongliang, vice president of Sany Heavy Equipment Mining Research Institute, introduced in Sany Heavy Equipment Xi'an Smart Factory: "The research and development of pure water brackets began in 2014, which stemmed from the urgent needs of coal mining enterprises for ecological protection. Through the three major technological innovations of pure water preparation process, closed liquid supply system and intelligent control technology, we have achieved a comprehensive upgrade of 'zero pollution, low cost and high efficiency'. ”

The pure water medium hydraulic system includes three parts: pure water preparation device, pure water high-pressure pump, and pure water support system. When the system is working, the mine water and drained water are used as the inlet water, and through the ultrafiltration system of the pure water preparation device, it enters the primary and secondary reverse osmosis, and finally enters the EDI (electrodeionization system) to produce pure water. The technology has passed the coal safety certification, has applied for 35 patents, including 16 invention patents, and won the second prize of science and technology progress of China Coal Industry Association. It has been applied in a number of coal mine projects in China, which perfectly interprets green mining.

Customer Cases:Reduce costs and worry, green and benefit win-win

Since the world's first set of pure water brackets was put into use in Shendong Jinjie Coal Mine in 2018, the technology has been used in many large state-owned coal enterprises such as National Energy Group, Shaanxi Coal Group, Shanxi Shenda Group, Hebei Jizhong Energy Group, Guizhou Anbao Group, Heilongjiang Longmei Group, etc., with a total of more than 30 million tons of coal mined, reducing emulsion consumption by 120,000 tons, equivalent to protecting 40 square kilometers of underground water bodies. At the same time, it has achieved zero mistakes and zero accidents.

The national strategy sets the tone:Green technology reshapes the economic logic of mines

Driven by the ecological protection policy of the Yellow River Basin, Sany pure water support has become a benchmark for the transformation of the coal industry.

"The ecological account is essentially the economic account," Zhang Zhihong, general manager of Sany Heavy Equipment, emphasized in an interview: "The pure water bracket proves that environmental protection investment is not a cost, but a return." Through the strategy of 'globalization, digital intelligence, and low-carbon', Sany will provide intelligent low-carbon solutions for the mining industry and contribute to the construction of Chinese-style modernization and ecological civilization." ”

In the face of the "double carbon" goal and the requirements of green mine construction, Sany Heavy Pure Water Hydraulic Support provides a sustainable development solution for the coal industry through three dimensions: media innovation, material upgrading, and intelligent empowerment. As presented in the CCTV documentary - the source of life of water human beings. Coal, the basic energy source for the operation of human society, allows pure water to drive the equipment, operates in the world under the mine, and continuously provides power for the operation of human society. The harmonious coexistence of man and technology provides all possibilities for the protection of green homes and the construction of ecological civilization.
