Black to green short board growth board -- look at the green development of Huangtolgoi Coal Company

Entering the Bayan Gaole Coal Mine of Huangtolgoi Coal Company of Northwest Mining of Shandong Energy Group, the camphor pine, spruce and cypress trees stand tall and straight between the mines, such as loyal guards, guarding the peace and harmony of the mining area.
Such a beautiful picture is the vivid portrayal of Huangtolgoi Coal Company's continuous expansion of green development space over the years.
Make gold by "light"
Approaching the distributed photovoltaic power station of Huangtolgoi Coal Company, I saw rows of blue solar panels, which continuously converted solar energy into electricity under the sunshine.
Huangtolgoi Coal Company is located in Inner Mongolia Autonomous Region, located in the northern frontier of China. Solar energy resources are abundant here, with an average solar radiation of 1653.5 KWH per square meter.
In order to make full use of solar energy resources, the company signed a power acquisition cooperation agreement with Inner Mongolia Tianyou Hengtai New Energy Technology Company to build a 5 MW distributed photovoltaic project in the coal mining subsidence area of Bayangaol mine field in Uxin Banner.
Huangtolgoi Coal Company has six systems of mining, digging, machinery, transportation, ventilation and drainage, and more than 5,900 sets of various types and sizes of equipment such as shearer, hoist and pump, which consume about 138 million KWH of electric energy annually.
"The use of photovoltaic treatment of coal mining subsidence areas can not only effectively use the ecologically fragile idle land, but also use solar energy to optimize the local energy structure, to achieve land use, power generation benefits and subsidence area governance 'triple win'." Meng Xin, secretary of the Party Committee, chairman and general manager of the company, said that under the "double carbon" goal, the company has changed unfavorable factors into favorable factors, changed short boards into long boards, and turned black mines into green mining.
It is understood that the distributed photovoltaic power generation project in the coal mining subsidence area of Bayangaole mining field in Wuxin Banner is divided into four phases. At present, the first three phases of photovoltaic projects have all been put into operation, with a total installed capacity of about 17 megawatts, using advanced P-type 550Wp (solar cell peak power) monocrystalline silicon single-side photovoltaic modules, a total of 10,504 photovoltaic panels have been installed, covering an area of 724.57 acres, and annual power generation of about 13.67 million KWH. The company can save about 3.56 million yuan of electricity and 2,590 tons of standard coal every year.
Among them, after the Phase III 5 MW project is connected to the 35 kV substation of the West wing wind well of the company, the daily real-time output of the photovoltaic power generation system in the access distribution section is less than the hourly electricity load of the access point, and green power access and on-site consumption can be achieved.
"Distributed photovoltaic power generation projects not only reduce the operating costs of enterprises, but also manage the subsidence area." The former land has become a green energy production base, and it has truly made money from light." Said Li Xiaobing, head of the company's mechanical and electrical management department.
Intelligent green
"Clear water and green mountains are Jinshan and silver mountains", into the company, the slogan on the publicity bar is particularly eye-catching.
Since the establishment of the mine, Huangtolgoi Coal Company has actively promoted the construction of green mines and won many honorary titles based on intelligent coal mining methods, standardized safety production, efficient resource utilization, clean production process, ecological mine environment and harmonious mining order.
The company regards scientific and technological innovation as a key engine for green development, and actively introduces cutting-edge technologies such as the Internet of Things, cloud computing and artificial intelligence in the whole process of coal mining, transportation and marketing.
"These smart devices can automatically adjust coal mining parameters according to the thickness and hardness of coal seams, achieve accurate mining, and reduce the waste of coal resources and the generation of pollutants such as dust." Ren Xuefeng, technical director of the company's fully mechanized mining area 1, said.
In the company's coal loading area, the intelligent loading system works methodically. After the vehicle enters the designated position, the intelligent loading system automatically identifies the vehicle type, load and other information, and then accurately carries out the loading operation, and the whole process is efficient and fast, without dust spillover.
In the coal transportation sector, the company has developed an intelligent environmental management platform. On the intelligent environmental management platform, the intelligent dust removal system automatically opens the spray dust removal device according to the dust concentration on the transportation line, achieving "intelligent management + closed-loop control".
"Our intelligent dust removal system can conduct real-time control, analysis, evaluation and decision-making for each subsystem, and realize fully closed management and dust removal in all aspects such as surface coal transportation, washing and temporary storage." Said Zhang Mingpeng, director of the company's entrepreneurship and innovation management center.
In the mine water treatment, the company invested 200 million yuan, built an intelligent mine water pretreatment station and mine water depth treatment station, the treated mine water quality in line with the "surface water environmental quality standards" Class III standards, the treatment capacity of 2000 cubic meters per hour.
"Part of this purified mine water is transported to chemical projects, and the other part is used for ground dust reduction, achieving full comprehensive utilization and zero emissions." Said Qiao Yanping, director of the company's environmental protection and energy conservation center.
