On September 8, China National Coal Association organized experts to evaluate the scientific and technological achievements of the “Integrated Research and Engineering Demonstration of Complete Equipment and Technology for Unmanned Intelligent Coal Mining Face” project led by Shendong Coal. After in-depth field inspections of the achievements and demonstration results of the unmanned intelligent coal mining face at Yujialiang Coal Mine, the experts unanimously agreed that the project reached the world-leading level.
With the goal of “achieving unmanned coal mining in the joint operation area of shearer, scraper conveyor and hydraulic support during coal mining operation at the mechanized mining face,” the project takes the work face of the No.43207 medium thick-thin coal seam of Yujialiang Coal Mine as a demonstration project. After nearly two years of tireless research, major progress has been made, creating a new unmanned coal mining mode of “ground planning of coal mining, automatic equipment operation, and unmanned operation in the mine face.” The project has realized unmanned work face during production and maintained continuous industrial application for more than six months. It can increase the coal mining efficiency by more than 20% compared with the traditional mode, providing the first set of industrial normalized application solutions for unmanned coal mining.
