The transformation development of the old mining area is a complex system engineering, it needs to command the overall situation by standing on the height of system engineering and needs to follow the harmonization in engineering, nature, science, technology, industry, economy and society. Engineering innovation is the main part of the technology innovations, it pushes the development of scientific, technical, industrial, economic and social, also the engineering innovation is relied on scientific and technological progress. Ecological protection is the premise of engineering development, and the ecological engineering construction is promoted by economic development. The protecting and mining of rare coking coal resources is a unity of oppisites. The companies of producting coking coal must pursue both immediate and long-term interests, especially the old mining, so the company should resolve the conflict between the scarcity of resources and the growth of demands by implementing limited exploitation, increasing resource recovery and efficiently recycling of coking coal resources to build the big-vertical-deep industry group. The conflict between frequent accidents and high input of existing security control promotes the development of security theory and technology, the transformation of security theory and technology from system security to structural security is a inevitable process of development.
