Metallic mineral resources development in China's development of circular economy


20nl level, the slope surface of the horizontal and vertical displacement component of node statistics, and draw horizontal deformation and tilt of surface deformation diagram,herve leger sale, and finally the use of horizontal deformation map to delineate the scope of a digging depth of the dislocation of the trend of increasing slope with unstable , to appear gradually increasing pressure, the stress level within the mining area is greater than the vertical stress, and surrounding rock strength is higher, likely to cause the accumulation of energy, reaches a certain level may induce rock explosion. Therefore, we should strengthen efforts to monitor slope and underground tunnel, and timely feedback to the production to avoid disasters.

Meanwhile, the development of mineral resource development of solid waste, water pollution, air pollution control and ecological restoration of supervision and management of land regulations, specifically dealing with J up to achieve a variety of standards to deal with the technical specifications to deal with corporate responsibility, rights and Zequan Li monitoring safeguards, oversight of the rights and responsibilities, misconduct penalties, so that mineral resource development companies and regulatory authorities, all the acts under the norms of the law. 4.2 to strengthen the policy-oriented, adhere to a combination of incentives and restrictions. Form a cycle of economic development incentives to improve the state's preferential policies for comprehensive utilization of mineral resources, full of preferential policies to encourage, guide and support the role: the development of research policy system to adapt to new situations, including financial, tax, financial, investment, technology promote the development of circular economy and other economic and technological policy 4.3 investments in technology, the development of circular economy to provide strong technical support for metal recycling economy development of mineral resources must rely on science and technology, to investments in technology, actively exploring new technologies, applications new technology, developing new equipment for mining enterprises to adjust the economic structure, change the mode of economic growth, to achieve the development of circular economy to provide technical support for countries to accelerate the development of mineral resources metal recycling economy project. '. The heart of the establishment, organization of major demonstration projects,Beats By Dre Studio! To address the cycle of economic development in the common and key technology focus; choose a symbolic target and widely applicable to future advanced technology, organization and implementation of a number of major demonstration projects, speed up the application of advanced technologies. Fund basic research in various countries, national research and other funded projects in the metal mineral resources development to increase funding for research investment. 4.4 strengthen the development of circular economy promotion of circular economy development is actually involved in the interests of all citizens, so the public should be the comprehensive utilization of resources, the backbone to achieve circular economy. Comprehensive utilization of resources to popularize scientific and legal knowledge, rational use of resources to enhance public awareness and responsibility, and correct guidance to mobilize public participation in comprehensive utilization of resources; to improve the social development and utilization of resources in a reasonable awareness of the importance to all the people to understanding, support and consciously involved in the cause of comprehensive utilization of resources, so step into a virtuous cycle of economic development track References 1 Ma to implement the scientific concept of development and vigorously promote the development of circular economy.
