The first domestic coal mine refrigeration system runs in Anhui Liujia Mine

“Since the use of coal mine cooling and cooling system, the fully mechanized mining face is much cooler!” This is the reporter’s 762-meter fully mechanized mining face in the Liuzhuang mine of Guotou Xinji Company. I heard the miners’ first domestic coal mine cooling and cooling system. Evaluation of operational effects.

Liuzhuang Mine is China's first digital deep mine with an annual output of 8 million tons. At the same time as the pilot production in October last year, SDIC Xinji Company equipped Liuzhuang Mine with an internationally advanced coal mine refrigeration and cooling system to form a capable force to inspect the cooling and cooling of several deep mines in Germany, Denmark, Sweden and South Africa. system. Carry out scientific research and independently design the cooling and cooling technology system of Liuzhuang Mine. With an investment of 7.5 million US dollars, the company has introduced coal mine refrigeration and cooling equipment from Germany's Simag, Botec and Siemens. At the beginning of this year, the installation of ground refrigeration units, pressure exchange systems and automatic control systems was in full swing. During the construction, SDIC New Collection Company installed more than 7,000 meters of refrigeration pipelines and 11 air coolers. Using the coal mine cooling and cooling system, the air temperature of the mining face of Liuzhuang Mine will not exceed 26 °C, thus meeting the requirements of the Coal Mine Safety Regulations.
