Intelligent Mining Technology for an Underground Metal Mine Based on Unmanned Equipment
This article presents facts and figures on mining equipment safety and reviews various important aspects of mining equipment safety including quarry accidents, electrical accidents, equipment fires, maintenance-related mining accidents, causes of mining equipment accidents and major ignition sources for mining equipment fires. A number of methods considered useful for performing mining equipment safety analysis are also presented. Useful strategies to reduce mining equipment fires and injuries, guidelines to improve electrical safety in the mining industry, and human-factor-related tips for safer mining equipment are discussed.
This article analyzes the current research status and development trend of intelligent technologies for underground metal mines in China, where such technologies are under development for use to develop mineral resources in a safe, efficient, and environmentally friendly manner. We analyze and summarize the research status of underground metal mining technology at home and abroad, including some specific examples of equipment, technology, and applications. We introduce the latest equipment and technologies with independent intellectual property rights for unmanned mining, including intelligent and unmanned control technologies for rock-drilling jumbos, down-the-hole (DTH) drills, underground scrapers, underground mining trucks, and underground charging vehicles. Three basic platforms are used for intelligent and unmanned mining: the positioning and navigation platform, information-acquisition and communication platform, and scheduling and control platform. Unmanned equipment was tested in the Fankou Lead-Zinc Mine in China, and industrial tests on the basic platforms of intelligent and unmanned mining were carried out in the mine. The experiment focused on the intelligent scraper, which can achieve autonomous intelligent driving by relying on a wireless communication system, location and navigation system, and data-acquisition system. These industrial experiments indicate that the technology is feasible. The results show that unmanned mining can promote mining technology in China to an intelligent level and can enhance the core competitive ability of China’s mining industry.
