Impact of natural resource mining on sustainable economic development:The role of education and green innovation in China

As the extraction and usage of natural resources continue to be a double-edged sword-supporting economic growth but deteriorating the environment-we study the impact of natural resource mining on sustainable economic development in the largest(PPP)economy-China.We use province-level data from 2001 to 2020 and employ econometric panel techniques,such as fixed effects,two-stage least squares,and a battery of robustness tests.We further explore the potential effects of education and green innovation in mitigating/exacerbating the role of natural resources in the Chinese provincial economy.The results show that:(1)Natural resource mining hurts sustainable development,verifying the“resource curse”effect.(2)Green innovation and education restrain the negative impact of resource mining on sustainable development,turning the curse into a blessing.(3)A regional heterogeneity is observed in the impact of resource mining on sustainable development,showing more significant effects in the Western and low-urbanized regions.(4)Green innovation and education can assuage the curse effect of natural resources into gospel effect.Policy implications and recommendations are proposed in light of the findings to promote sustainable economic development in China.

Some Challenges of Deep Mining

An increased global supply of minerals is essential to meet the needs and expectations of a rapidly rising world population. This implies extraction from greater depths. Autonomous mining systems, developed through sustained R＆D by equipment suppliers, reduce miner exposure to hostile work environments and increase safety. This places increased focus on ＂ground control＂ and on rock mechanics to define the depth to which minerals may be extracted economically. Although significant efforts have been made since the end of World War II to apply mechanics to mine design, there have been both technological and organizational obstacles. Rock in situ is a more complex engineering material than is typically encountered in most other engineering disciplines. Mining engineering has relied heavily on empirical procedures in design for thousands of years. These are no longer adequate to address the challenges of the 21st century, as mines venture to increasingly greater depths. The development of the synthetic rock mass （SRM） in 2008 provides researchers with the ability to analyze the deformational behavior of rock masses that are anisotropic and discontinuous-attributes that were described as the defining characteristics of in situ rock by Leopold Mfiller, the president and founder of the International Society for Rock Mechanics （ISRM）, in 1966. Recent developments in the numerical modeling of large-scale mining operations （e.g., caving） using the SRM reveal unanticipated deformational behavior of the rock. The application of massive parallelization and cloud computational techniques offers major opportunities： for example, to assess uncertainties in numerical predictions： to establish the mechanics basis for the empirical rules now used in rock engineering and their validity for the prediction of rock mass behavior beyond current experience： and to use the discrete element method （DEM） in the optimization of deep mine design. For the first time, mining-and rock engineering-will have its own mechanics-based Ulaboratory.＂ This promises to be a major tool in future planning for effective mining at depth. The paper concludes with a discussion of an opportunity to demonstrate the application of DEM and SRM procedures as a laboratory, by back-analysis of mining methods used over the 80-year history of the Mount Lvell Copper Mine in Tasmania.

Integration system research and development for three-dimensional laser scanning information visualization in goaf

An integration processing system of three-dimensional laser scanning information visualization in goaf was developed. It is provided with multiple functions, such as laser scanning information management for goaf, cloud data de-noising optimization, construction, display and operation of three-dimensional model, model editing, profile generation, calculation of goaf volume and roof area, Boolean calculation among models and interaction with the third party soft ware. Concerning this system with a concise interface, plentiful data input/output interfaces, it is featured with high integration, simple and convenient operations of applications. According to practice, in addition to being well-adapted, this system is favorably reliable and stable.

Study on International Development of Financial Asset Securitization:An Example of Mining Rights

Mining right asset securitization is a market financing pattern for mineral resources, and it is a creative application of financial asset securitization. Nowadays, because of world energy price decline, the world energy market is facing weak investment and financing sharply under pressure. Under this background, this paper aims at briefly commenting on the content, processes and impact of mining right asset securitization, understanding the international mining right asset securitization specific practices, and then combining the situation of China(Shanghai) Pilot Free Trade Zone so as to give advice for the development of mining right asset securitization in China. For instance, mineral mining rights and expenses system design are not clear, so the mineral values do not reflect their true costs and the need to speed up market credit system construction.
