Over the past year of integration and reorganization, Jinneng holding group has opened a new situation in the changing situation, adhered to the road of “reduction, optimization and green”, continuously improved the proportion of advanced production capacity, accelerated industrial transformation and upgrading, promoted high-quality development in an all-round way, and worked hard to realize the vision of “carbon neutrality”.
scientific and technological innovation helps enterprises show their role as
Intellectualization has fundamentally changed the operation mode and working conditions of coal miners. Now, the workers of Jinneng holding group can command the machine to cut coal sitting in the central control room. Ren Jinfeng, the monitor of the first fully mechanized mining team of Sihe mine of Jinneng holding coal industry group, said: “after the self-moving train and advanced support are put into operation, not only the operation efficiency is improved, but also the safety factor is more guaranteed. It will soon become history to drive a single column to advance the maintenance of the roadway.”
The intelligent system can realize the “network car Hailing” of calling in and out of the well with mobile phones. Technicians can solve equipment faults underground through mobile phone video guidance, Siasun Robot&Automation Co.Ltd(300024) automatic patrol inspection, remote control of heading face, full coverage of 5g network up and down the well, and underground real-time mobile phone video communication are vivid practices of scientific and technological innovation achievements.
Meanwhile, Jinneng holding group is actively cultivating advanced production capacity and building smart mines. At present, the three mines of Tashan, Tongxin and Majialiang have achieved full coverage of 5g network up and down the shaft, and all 65 intelligent fully mechanized mining faces have realized the unattended and remote monitoring of underground fixed posts, intelligent decision-making and automation of various systems, and the production capacity of intelligent equipment has reached 89 million tons.
The first scientific research and innovation Artificial Intelligence Computing Center in the national coal industry jointly built by Jinneng holding group and Huawei aims to use Huawei’s key technologies accumulated in the ICT field to improve the digital and intelligent level of coal mines and help coal mines achieve “safety, few people, no one and high efficiency”.
In 2021, Jinneng holding power group started the “green power” mode. “Smart power plant” is one of the key links. Tashan power generation company, as a pilot of “smart power plant” transformation project of Jinneng holding group, has completed the transformation of all “smart power plant” projects so far.
The coal mine intelligent power supply system and high-end electrical products independently developed and produced by Anyi electric of Jinneng holding equipment manufacturing group have obtained the national safety standard certificate. After the power supply system is operated, only one person can remotely control the power supply equipment 100 meters underground during patrol inspection, and the operation of underground equipment will be uploaded in real time in the form of data and video, Carry out data analysis and fault early warning, and can replace 3-4 employees to work at the same time.
develop clean energy and activate the driving force of development
Jinneng holding power group clean energy company has become the largest clean energy enterprise in Shanxi Province. The photovoltaic cell shipments of Lu’an Cecep Solar Energy Co.Ltd(000591) company rank fourth in the world, with an average daily output of 2.2 million high-efficiency cells and a battery photoelectric conversion efficiency of 22.8%.
At present, Jinneng holding power group has built a clean energy industrial system integrating wind, light, water, gas and gas power generation + photovoltaic manufacturing plant. Its subordinate Jinneng Holding Shanxi Electric Power Co.Ltd(000767) recently acquired Shanxi Tianqiao Hydropower with full shares, with a generator assembly capacity of 128000 kW. The hydropower generated by the Yellow River flow enters the power grid through the transmission line and is mainly sold to the State Grid Shanxi electric power company and Shaanxi Yulin power supply company. The acquisition further optimized the power structure, gathered high-quality resources and expanded the scale of clean energy power generation business.
As one of the first national photovoltaic demonstration bases in China, Zuoyun 100000 kW photovoltaic power station has an annual average on grid power of 180 million kwh, and built the country’s first 286 meter long photovoltaic pavement and photovoltaic corridor integrating utility and power generation, so as to maximize the efficiency and benefits of photovoltaic power generation.
Next, Jinneng holding power group will further gather advantageous resources and continuously expand to 15 aspects such as distributed photovoltaic, biomass power generation and geothermal power generation on the basis of existing photovoltaic, wind power and other projects.
Yanzishan mine sewage treatment plant of Jinneng holding coal industry group uses heat source pump for heating in winter, which is far lower than the cost of coal-fired heating, and the cost per square meter is only 0.9 yuan. The mine water reprocessed by the water plant meets the standard of drinking water, and is recycled in surface and underground systems, with remarkable environmental and economic benefits.
At the same time of resource exploitation, Jinneng holding group has treated the ecological environment of the mining area, and continuously promoted the transformation of boiler flue gas desulfurization and dust removal, the construction of coal-fired boiler flue gas denitration system, ultra-low flue gas emission transformation and other projects. In 2020 alone, 80 coal-fired boilers in each mine will be upgraded and optimized for desulfurization and dust removal, 45 coal-fired boilers will be transformed for flue gas denitration technology, and 3 130 steam ton boilers in Guangfa chemical company of coal industry group will be transformed for ultra-low flue gas emission, so as to reduce coal consumption and carbon emission.
Jinju coal electrification company of Jinneng holding equipment manufacturing group uses gas to generate electricity and realizes the circular economy mode of cogeneration. For 12 consecutive years, the company’s gas power generation has ranked first in China. As the first “smart gas power plant” in China, lujiayu phase II gas power generation project of Jinju coal electrification company has an installed capacity of 16 1500 kW container gas-fired generator units, supporting waste heat boiler, flue gas purification system, electrical system and thermal control system. The power station was officially put into operation on December 9, 2020, with a total installed capacity of 27 MW. We have truly made gas become “waste” into treasure and “harm” into benefit.
polish the ecological background and share “green benefits”
The fully enclosed coal storage shed, coal storage bunker and belt transportation corridor of Tashan mine of Jinneng holding coal industry group can reach the main wellhead, transport the raw coal to the bulk workshop, raw coal bunker, coal washing plant and clean coal bunker through the fully enclosed belt trestle, and then load the coal for outward transportation. The whole coal flow transportation is highly closed, and the cinder can not be seen outside.
In 2020, Jinneng holding group has 28 coal storage yards with an area of about 100000 square meters, which have been completely closed, so as to truly realize no coal in coal mining and no coal exposure in coal storage. In 2021, Jinneng holdings group added 366500 square meters of green space, with a green coverage rate of 33.62%. It built 17 sewage and wastewater treatment plants, eliminated 258 1634 ton steam coal-fired boilers, completed an environmental protection investment of 2.368 billion yuan, realized the comprehensive treatment and ecological restoration of 24 waste dumps and 6 fly ash storage yards, and completed 34 waste dump railing dams The construction of supporting facilities such as flood discharge channels and waste transportation roads, and the project of “treating the root causes on the mountain and increasing green around” make the “coal sea into an oasis” no longer a vision.
