Safety is paramount in coal production. In 1986, he graduated from the Mining Department of Fuxin Institute of Mines and came to Yangmei Minmetals Group with his passion for the coal industry. He has been dedicated to ventilation management and gas control for more than 20 years. With his rich ventilation gas control practices and technologies, he has supported a blue sky for the safe production of Minmetals. He is also the first inventor of the "triple interlock detonator". He is Wang Dongping, the mine manager of Yangmei Mining Mines.
The research results he participated in, "Research on Technology and Adaptability of the First-time Unstable Gas Eruption Control on the Roof of the Mechanized Caving Surface", were reviewed by experts organized by the Shanxi Provincial Department of Science and Technology in 2006 and reached the international leading level. The project has achieved remarkable results in production applications, shortening the initial mining period of the fully mechanized caving roof from an average of 40 days to about 15 days. Each working face can produce an additional 150,000 tons of raw coal, creating an economic benefit of 25.724 million yuan. Calculated based on the 18 working faces that can be mined each year, an additional 2.7 million tons of raw coal can be produced, creating a value of 463.752 million yuan.
The research project he participated in, "Research and Application of Mining Technology under Loose Coal Roof Conditions in High Gas Mine Collapse Pillar-Dense Areas", was appraised and reviewed by relevant experts organized by the Shanxi Provincial Department of Technology in 2006 and reached Internationally leading level, it has improved the gas control effect, accelerated the passage time of collapse pillars, successfully solved the problem of full coal tunnel support in soft and broken coal seams, and achieved effective control of the surrounding rock of the tunnel; comprehensively integrating Yangquan 15# Coal seam gas control technology ensures safe mining of high gas coal seams with dense collapse pillars. Experts commented that the research results of this project are wide-ranging and difficult, and have achieved the goal of safe and efficient mining under the complex geological conditions of Minmetals. The benefits are significant and have reached an international leading level. level. It is estimated that the economic benefit will be more than 300 million yuan.
The national "Ninth Five-Year Plan" key project he participated in "Research on Safety Guarantee Technology for Mining of High-Gassy and Spontaneous Coal Seams with Fully-Mechanized Caving Faces" was recognized by the state. Two of the sub-topics reached the internationally advanced level, and three of the sub-topics reached the international advanced level. Reaching the domestic leading level. These scientific research results have contributed to the realization of Minmetals' intrinsically safe, high-yield and high-efficiency projects and the realization of the group's grand goal of "strengthening with great strength and achieving 30 billion in ten years".
