Xinjiang Zhundong allows black coal to achieve green development

Recently, the reporter saw at the coal loading site of Xinjiang Tianchi Energy Co., Ltd. in the Zhundong Economic and Technological Development Zone of Xinjiang that coal trains were entering the ring hopper for coal loading operations.

"This was not the case a few years ago. At that time, railway transportation did not really play a major role." According to Liu Wei, Manager of Zhundong Business Department, Urumqi Freight Center, China Railway Urumqi Bureau Group Co., Ltd., Zhundong Development Zone produced 44 million raw coal in 2016. The 257-kilometer-long Uzbekistan-Zhunjiang Railway has only 3.8 million tons of coal transported. It is mainly transported by road. During peak hours, more than 5,000 smoky coal trucks enter and exit Zhundong, which not only provides road traffic safety belts. Hidden dangers, vehicle exhaust and coal ash dust also have a great impact on the surrounding environment.

Since 2016, the railway department has implemented measures to increase the capacity of the Uzbekistan-Zhunjiang Railway. A major transformation of the coal transportation model has spread in Zhundong. The long queue of coal transportation vehicles has been quickly replaced by trains, which has caused a major change in the coal transportation pattern of Zhundong. Variety. Last year, Zhundong's coal output was 57.42 million tons, and the coal transportation volume of Wuzhun Railway soared to 21 million tons. It is estimated that the railway coal transportation capacity will reach 38 million tons this year, accounting for more than half of coal production. As the coal transportation volume of the Wuzhun Railway continues to grow, its advantages of environmental protection, speed, and large transportation continue to appear.

Shi Haisheng, member of the Party Working Committee and Deputy Director of the Management Committee of Xinjiang Zhundong Economic and Technological Development Zone, introduced that the Zhundong coal field has shifted from road transportation to railway transportation. Compared with last year, Xinjiang Tianchi Energy Co., Ltd. The total amount of coal diverted to railway transportation is equivalent to a reduction of more than 300,000 vehicle trips in automobile transportation, which has a positive effect on ecological protection.

　　 On the same day, in the Wucaiwan No. 3 open-pit coal mine in Zhundong Development Zone, a 17-meter electric forklift was working in the pit. The reporter saw that after coal is mined from the mine, it is directly put on the blue coal conveying corridor conveyor belt. The coal conveying corridor is closed for transportation and directly transported to the power plant, effectively reducing environmental pollution.

“Currently, the coal conveying corridor can transport 27,000 tons of coal a day. When converted into a 40-ton truck, it takes nearly 700 vehicles to complete.” Meng Hexin, general manager of Xinjiang Jiuhuatian Logistics Co., Ltd., pointed to the windbreak not far away. The dust suppression net said, "Now this net is useless. Coal used to be piled up in the open air, so this net was set up. Now that coal is transported without the sky, there will be no coal dust pollution."

　　 Currently, Zhundong Electric Power has a total installed capacity of 27.97 million kilowatts. In order to achieve high-efficiency and low-polluting coal transportation, Zhundong Development Zone has built four coal conveying corridors with a total length of about 100 kilometers. Coal enters the power plant along the coal conveying corridors, which is both efficient and environmentally friendly. In the future, Zhundong Development Zone will build three more coal conveying corridors with a total length of about 50 kilometers.

　　 In the eyes of others, fly ash is waste residue, but in the eyes of Zhao Xingang, general manager of Wucaiwan Shayuan New Building Materials Co., Ltd. in Zhundong Economic and Technological Development Zone, Xinjiang, it is a treasure. On the same day, the reporter saw in the company that raw materials such as fly ash, cement, lime, and gypsum were steamed in the machine just like steamed buns. After 10 hours of "kneading, waking up, cutting, and autoclaving", A new green and environmentally friendly building material-autoclaved aerated concrete slab.

　　 In February 2018, the material obtained the "Certificate of New Type Wall Material Certification" by the relevant departments of the autonomous region. Zhao Xingang introduced that as an enterprise engaged in comprehensive utilization of fly ash, the company's new building material manufacturing base can consume more than 300,000 tons of industrial waste residues every year.

"We use the industrial wastes such as fly ash, slag and desulfurized gypsum formed in the production of coal power and coal chemical companies to vigorously develop new wall materials, furniture decoration and other new building materials, and adopt the method of recycling and squeezing out , Turning the current 2.5 million tons of solid waste per year into usable resources, all of which have been effectively transformed and utilized, and a green industry development path has been constructed.” Shi Haisheng said.

No coal is found in coal mining, water is recycled, waste residues and ash are also "dried and squeezed out". Coal-related enterprises have ultra-low or even zero emissions. Zhundong Development Zone is passing strict implementation of industry access, environmental access conditions and clean production standards , Let black coal achieve green development.
