The 44 base stations underground achieve full coverage of 5G signals, high-definition audio and video calls above and below the well, robots to inspect underground water pumps, and workers’ remote-operated comprehensive excavators 50 meters away to ensure personal safety... At the Dongshan Coal Mine of Jixi Mining Company, Longmei, Heilongjiang, "5G + Wisdom" The construction of "mines" is in full swing, and safe and high-quality coal production capacity has been continuously released.

　　Jixi City, with a history of 115 years of coal mining, is rich in coal, graphite and other minerals, and the Wusuli River and Xingkai Lake are beautiful.

From "one coal dominance" to building "China's graphite capital" and "eco-tourism city" two city cards, Jixi is based on the coal pillar industry, enhances the ability to guarantee energy security, and promotes the development of graphite and other non-coal industries.

　　Eliminate small coal mines to release high-quality production capacity

　　Jixi was established because of coal, prospered because of coal, and changed because of coal.

　　Jixi is a coal base constructed during the “First Five-Year Plan” period of my country. It has experienced extensive development for a long period of time. Hundreds of coal mines are blooming everywhere, environmental pollution, development disorder, and mining disasters occur from time to time.

In the new era, the old road of extensive development will not work, and high-quality development needs to be solved urgently.

　　In 2016, Jixi officially opened the curtain of reducing coal production capacity, sounding the clarion call for coal city transformation.

Coal mines that have a single well production capacity of 150,000 tons/year or less and do not have the capacity to expand to 300,000 tons/year or more will be closed and exited.

In addition, the continuous downturn in the coal market in previous years has caused Jixi's economy to be hit in the short term.

　　The arduous process of eliminating outdated coal production capacity has allowed Jixi to see the future.

The Jixi mine has been reduced, but the production capacity has increased significantly. It is vividly called by the Jixi people as "the bungalow and the building".

"The production capacity indicators of local small coal mines are not only digested locally, but also some non-local indicators have to be purchased to increase coal production capacity." Lin Maochuan, deputy director of the Hengshan District Coal Production Safety Administration, Jixi City, explained.

　　Wang Xinyu, Chief of Coal Section of Jixi Development and Reform Commission, told reporters that during the "Thirteenth Five-Year Plan" period, Jixi has achieved phased results in eliminating outdated coal production capacity. A total of 87 local coal mines have been closed and withdrawn, and 7.27 million tons of production capacity has been eliminated and resolved per year.

Jixi plans to retain 79 coal mines and build 2 new coal mines.

By the end of the "14th Five-Year Plan" period, Jixi's coal production capacity will increase from the current 12 million tons per year to 40 million tons.

　　Recently, the National Development and Reform Commission issued the "14th Five-Year Plan for Promoting the High-quality Development of Resource-Based Regions", emphasizing that resource-based regions must ensure national resource and energy security.

For Jixi, eliminating outdated coal production capacity and releasing high-quality coal production capacity are the responsibilities that the coal city must shoulder for its transformation and development.

The removal of the old coal industry in Jixi is now providing strong support for the transformation and development of Jixi.

　　Build smart mines to empower old mining areas

　　Safety in production is the top priority of coal mines.

To ensure national resource and energy security, we must focus on security from the source and ensure supply.

Today, the construction of 5G+ smart mines makes it possible for coal mines to be safe when there are few people, and safe when no one is there.

　　At present, the problem of the aging of the coal mine workforce in our country is widespread. In addition, the depth and difficulty of mining in some old mining areas are gradually increasing. It is necessary to pass the technological revolution of "substituting "machines" for people and "machines" for people to retreat" to achieve underground safe production and improve Coal production capacity.

This year, Longmei Jixi Mining Company's Dongshan Coal Mine "5G + Smart Mine" construction has achieved initial results, becoming the first "5G + Smart Mine" project in the coal industry in the three northeastern provinces.

　　Through the construction of "5G+smart mine", Jixi's century-old mining area is rejuvenated.

“In the past, coal miners went down and wanted to contact them. It was a “needle in a haystack”. In emergency situations such as equipment failure, water penetration, landslides, etc., it was difficult for the ground to provide effective guidance to the underground.” In the Dongshan Coal Mine Production Information Command Center, Electromechanical Deputy Chief Engineer Gao Yueqing pointed to the big screen and told reporters that the construction of "5G + smart mines" is making coal mine production safer and more efficient.

　　Dongshan Coal Mine, which was built in 1950, was the first local production mine to realize intelligent coal mining.

"The intelligent fully mechanized mining face started trial operation on December 20 last year. In April this year, it completed a single-month raw coal output of 116,000 tons, creating the highest level of fully mechanized mining of 1.5 meters thin coal seams in Long Coal Group." Gao Yueqing told reporters that the intelligent comprehensive mining The mining face has formed a new safe production mode of "visual remote intervention".

Following the advance of the fully mechanized mining machine through the video of the hydraulic support, the workers can operate at a distance of 50 meters behind the machine, and the entire operation process can also receive effective guidance from the ground.

The number of employees in the intelligent fully mechanized mining face has been reduced from 110 to 55, which has halved the workforce, doubled the production capacity, and doubled the income of the workers.

　　The investment in the construction of "5G+smart mines" is high. The investment in the intelligent transformation of Dongshan Coal Mine alone is as high as 80 million yuan, but the changes brought about by coal safety production are obvious.

Unmanned mining is no longer an unattainable dream.

　　"Through 5G applications, it is possible to accurately and comprehensively obtain various underground safety production data and environmental videos, realize underground and underground audio and video calls, as well as rapid data transmission, equipment remote control and other applications, which will transform the intelligent working face of Dongshan Coal Mine. Remote intelligent control and related data automatic monitoring and real-time interconnection provide technical support for intelligent ventilation and intelligent transportation." Gao Yueqing said.

　　"Smart mine construction and intelligent mining are the development direction of the coal industry, and are also the core technical support for the high-quality development of future enterprises." Jixi Mining Company Secretary of the Party Committee and Chairman Liu Xianjun said that we must make efforts to integrate with cutting-edge technology and press Smart Mines The construction of the "fast-forward key" strives to achieve the goal of safe, efficient and high-quality development of coal mines, and enhances the ability to guarantee energy security.

　　Industrial transformation enhances urban competitiveness

　　Coal and graphite are called "two blacks" by Jixi people.

As one of the largest high-quality flake graphite deposits in the world, Jixi has a proven resource of 976 million tons.

Jixi takes the graphite industry as the main direction of industrial transformation to build "China's Graphite Capital".

　　In Hengshan District, the Liumao graphite mine, which has been mined for more than 80 years, is still the largest graphite mine in the area.

Heilongjiang Pride New Material Technology Co., Ltd. is the "new owner" of Liumao Mine.

Pride Company was jointly initiated and established by Beijing Automotive Group Co., Ltd. and the Jixi Municipal Government. It will become an integrated new material enterprise integrating graphite mining and selection, lithium ion battery anode materials, graphene and other graphite deep processing integration.

　　"After the'dual carbon' goal was proposed, the new energy industry ushered in a new round of opportunities. Graphite, as a strategic mineral resource, is an important raw material for the manufacture of negative electrode materials for power batteries." Huang Yizhen, deputy general manager of Pride, told reporters. With the rapid development of the new energy automobile industry, the cost of artificial graphite remains high, and the market price of natural graphite anode materials is also "upward", and the market prospect is broad.

The transformation of Jixi's graphite industry from extensive to high-quality development requires grasping the new energy industry's "outlet."

　　For a long time, the focus on graphite mining and selection and insufficient deep processing capacity have become the bottleneck restricting the development of the graphite industry in Jixi.

Today, this bottleneck is being broken.

In 2020, the output of Jixi graphite powder is 350,000 tons, accounting for 40% of the national output, and the deep-processed products are 215,000 tons.

Li Wei, director of the Graphite Office of the Jixi City Bureau of Industry and Information Technology, told reporters that Jixi has vigorously promoted the transformation of graphite resources from extensive mining to intensive processing, and industrial upgrading and upgrading have exerted efforts in many fields.

　　Jixi took the lead in forming the National Graphite Industry Technology Innovation Strategic Alliance, built 8 "National Brand" and "Provincial Brand" scientific research platforms, and 19 graphite high-tech enterprises; successfully broke through the technological bottleneck of domestic large-diameter artificial single crystal diamonds and achieved the largest single crystal Large-scale mass production of 15 carats; industry-leading research results have been achieved in natural graphite anode materials, graphene oxide synthesis, and fluorine-free purification technologies, which have promoted industrial innovation and development.

　　Jixi has also become the maker of graphite industry standards.

The National Graphite Product Quality Supervision and Inspection Center (Heilongjiang), and the National Non-metallic Mineral Products and Products Standardization Technical Committee Flake Graphite Subcommittee have successively settled in Jixi.

“At present, we have formulated 16 local standards for the graphite industry, and are formulating and revising one national standard and one industry standard. Jixi is becoming a leading place for graphite industry standards.” Liang Aimin, director of the National Graphite Product Quality Supervision and Inspection Center (Heilongjiang) Said that it is necessary to actively promote the coordinated development of standard research, technological innovation and industry, and promote the efficient use of graphite resources and the upgrading of the graphite industry.

　　Ussuri boat songs are melodious, and Xingkai Lake is surging.

In Jixi, coal and graphite resources are black, but Jixi insists on green development unswervingly. While industrial transformation drives urban transformation and development, it pays attention to the protection of green waters and mountains. The beautiful Jixi, which is surrounded by black and green, is accelerating: the coal industry is reborn. , The strong rise of the graphite industry, the continued growth of the green food industry, and the accelerated development of the pharmaceutical industry... During the "14th Five-Year Plan" period, Jixi will make every effort to extend the chain, expand the chain, supplement the chain, and strengthen the chain, promote the accelerated conversion of new and old kinetic energy, and strive to achieve a production city Prosperity, to explore the experience of Jixi for the high-quality transformation and development of resource-based regions.
