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.
Mining is one of the oldest industries in the world. environmental protection equipment techniques have passed through a rapid change from artificial production, mechanized production, and on-site remote-control production, to intelligent and fully automated production. In order to move the mining industry forward, mechanization tools have been developed, single-equipment and independent systems have been automated, and the entire mining production process has been highly automated . By integrating information technology with the industrialization of mining technology, intelligent mining technology has been rapidly developed, based on mechanized and automated mining, as shown in Fig. 1. This has resulted in the gradual upgrading of intelligent processes in mining equipment; unmanned and centralized mining equipment have now entered the stage of practical application, which will significantly advance the automation and information technology used in mining .
Intelligent trackless mining technology is based on intelligent unmanned equipment at the executive layer, such as rock-drilling jumbos, DTH drills, underground scrapers, underground mining trucks, or underground charging vehicles. The functions of intelligent and unmanned diamond mining equipment differ according to the different tasks each piece of equipment must carry out.
Rock drilling is the key process in mining, and plays a very important role in productivity, cost, and efficiency. Different geological conditions require different mining methods, and different methods require different types of rock drilling. A hydraulic rock-drilling jumbo is needed for medium-length hole drilling (i.e., depth of 20–30 m, diameter of 60–100 mm) . An intelligent and unmanned rock-drilling jumbo has been designed to support intelligent mining technology and efficiently complete drilling work.
Remote control and a virtual-reality display were the first basic technologies implemented in the unmanned hydraulic rock-drilling jumbo. Fig. 4 shows the initial unmanned control platform for the jumbo on the surface. The virtual prototype display system, including on-site audio and video signals, is well-integrated in order to increase the feeling of immersion while performing remote-control operations.
