The problems are related to the ignorance of the managers and the workers, a lack of capital, the insufficiency of occupational health services, and the transfer of some hazardous work from large factories in the cities to small plants in the towns and villages. The change in life-style, especially in smoking habits, has aggravated occupational hazards. The problems may be solved by renewing the concept of health among the managers and workers, enforcing legislation related to occupational hazards, strengthening health personnel training, and reinforcing health education and self-help. 1989 Academic Press, Inc.展开更多

This paper summarizes this great achievement, which occurred during the 12th Five-Year Plan (2011-2015), and which included the development of a set of intelligent equipment for hydraulic-powered supports, information transfers, dynamic decision-making, performance coordination, and the achievement of a high level of reliability despite difficult conditions. Within China, the intelligent system of a set of hydraulic-powered supports was completed, with our own intellectual property rights. An intelligent mining model was developed that permitted unmanned operation and single-person inspection on the work face. With these technologies, the number of miners on the work face can now be significantly reduced. Miners are only required to monitor mining machines on the roadway or at the surface control center, since intelligent mining can be applied to extract middle-thick or thick coal seams. As a result, miners' safety has been improved. Finally, this Darter discusses theprospects and challenges of intelligent mining over the next ten years.展开更多
