Joint innovation between public and private enterprises: the joint creation of the new chapter of the "three high and four new" - deputy chief executive Liu Weidong and group leader Shi Fengan visited Feny.

April 8, member of the party group and deputy director of Hunan Provincial Department of Industry and Informatization Liu Weidong, head of the inspection team for discipline supervision under the Provincial Inspection and Control Committee, as well as a member of the party group of the department Shi Fengan with a delegation visited several enterprises in Changsha to conduct research, focusing on the effectiveness of the implementation of the "three high, four new" strategy. As a leading enterprise in the field of global solid waste liquid filling technology, Feny Co., Ltd. (hereinafter referred to as “Feny”) through its scientific and technological innovation and achievements in green production has become an important stopping point in the course of research, demonstrating the powerful power of advanced production and scientific and technological innovation of Hunan Province.

Brief description of the research activities:

At 11:55 a.m., the research team arrived at Feny. Visitors visited the R&D center for the development of granular material filling system technologies in mines, the National Laboratory of Filling Materials and the Pilot Center for Granular Material Filling, where they got acquainted in detail with the company's complete production chain in the field of filling method extraction technologies, innovative achievements in the development of granular material filling technologies for solid waste, equipment manufacturing and environmentally friendly transformation. Feny Chairman Zhang Zhou gave a special presentation to the group of key results of corporate technologies, advanced international comprehensive solutions for filling granular materials, as well as practices of environmentally oriented development under the conditions of "double carbon" goals.

Joint-stock company Feny: scientific and technological innovations create a global benchmark Feny, being a national enterprise "key small giant" in the field of specialization and innovation, has been actively developing the field of solid waste filling with paste for more than a decade. Based on the principles of "technology autonomy, equipment intelligentization and service globalization", the company has created a number of industry benchmarks:

Breaking the monopoly: self-developed industrial paste filling pumps and deep cone separators have filled the internal gap, ending the foreign technology monopoly; Leading standards: lead the development of 3 national standards and 4 group standards, lead the development of one industry standard. Participation in major scientific and technological projects of the country within the framework of the 14th five-year period; Patent barrier: more than 500 patents, including more than 180 inventions, fully independent and controlled key technologies; scientific and technological achievements have received more than 20 prestigious awards, including the first prize of China coal industry.

Honor and honor: receiving more than 30 scientific and technical awards, including the title of national "Green Factory", semi-factory test site, Hunan Province intelligent manufacturing demonstration workshop, as well as internationally recognized model enterprises.

Key Technologies: Breakthrough and Benefits of Solid Waste Paste Filling Technology

More than 10 key solid waste treatment plants developed by Feny in-house, including industrial paste filling pumps, deep cone concentrators and continuous two-axis mixers.

Technical principles

Using the technology of preparing highly concentrated pastes from solid waste,such as mine tails and coal glinobite, are mixed with cement materials to obtain a paste-like suspension with high fluidity and stability. It then accurately fills the underground quarries, achieving a dual goal: zero solid waste emissions and the safe removal of voids in the quarries. High efficiency and energy saving: the filling concentration can reach 75-85%, which saves 40% of water compared to traditional technologies and reduces energy consumption by 30%;

Safety and environmental friendliness: the high strength of the filler effectively prevents the collapse of the earth surface, reducing the damage to the environment when mining.

System Compatibility: The Feiyi filling system is based on the principles of “intelligent Internet of Things and algorithms”, combining the technologies of various subsystems to achieve the desired filling effect in different conditions of mining enterprises.

Smart control: the integration of the Internet of Things and artificial intelligence algorithms to fully automate the monitoring and dynamic regulation of the refuelling process.

In the rhythm of the "three high, four new" strategy

Feny's practice is a vivid example of the implementation of the "three high, four new" strategy of Hunan Province:

High-tech Industrial Center:

The world's only enterprise, Providing comprehensive solutions for filling solid waste in the form of paste for all mining mines, the equipment is exported to countries passing the “One Belt, One Road”, contributing to the output from Hunan to the world level.

High-tech Innovation Center:

Based on research platforms,such as the key laboratory of the National Administration for Supervision of Mining Safety, together with universities develop key technologies to promote the intelligentization and transition to a low-carbon model in the industry.

Responsibility for green development:

With the help of paste filling technology, the resource utilization of solid waste is achieved, pollution in mining is reduced, more than 100 million tons of solid waste are processed annually, which provides technical support for achieving “peak carbon emissions” and carbon neutrality. Deputy Chief Executive Officer Liu Weidong highly appreciated Feny's innovation potential and social responsibility, Emphasizing: “The enterprise should continue to be guided by the principles of “three high and four new” (high level of technology, high production efficiency, high competitiveness, new technology, new products, new methods and new management) deepen the integration of science, education and manufacturing, take a leading position in technology, and contribute to the establishment of a global cluster of advanced machinery in Hunan Province.” Group leader Shi Fengan pointed out that Feny's green transformation path has become a model for the industry, and expressed the hope that in the future, with the support of public policy, more scientific and technological achievements will be transformed into productive forces.

This study underscores the government’s recognition of Feny as the benchmark for intelligent manufacturing in engineering technologies of Hunan Province’s green mining enterprises. As part of Feny’s “Three High, Four New” strategy, based on the principles of “Technology Leadership + Green Mining”, Feny is committed to:It has not only become a model for the implementation of the strategy of the Changsha City Global Research Center, but also demonstrated the global power of Chinese intellectual production. The company will continue to deepen its work in the field of solid waste processing, using technological breakthroughs to drive industry transformation and bring environmental impetus to the sustainable development of global industry and mining.
