This study is based on China's DIG and explores its impact on regional mineral resource dependence (NRD) in 30 provinces of China. We find that, with a 1% increase in . SYNOPSIS. In October 2024, China’s first comprehensive regulation to tighten state control over the critical sector of rare earth resources took effect. Coming amid the global transition towards clean energy, the regulation demonstrates China’s increased leverage of its rare earth monopoly to outpace its geopolitical rivals like the United States, which remains far . Nonexplosive mechanical excavation technology and techniques are being developed to enable metal mines to operate on a single operating surface, using a single mining machine for multiprocess parallel continuous operation. These advancements aim to address the key challenges of intelligent mining.
enhanced mining technology
Through a major scientific project, Central China's Hunan Province has made breakthroughs in key equipment and technology for deep-sea mineral resource exploration, some of which have filled. This article reviews the key engineering technologies to achieve green, intelligent, and sustainable development of deep metal mines in China, such as rockburst prediction, support, and cooling. It also discusses the major problems and challenges of deep mining, such as high stress, lithology deterioration, and high temperature.
The gob-side roadway technology is widely used in coal mining in China, as it can improves the recovery rate of coal resources and alleviate the shortage of mining replacement. However, it is still difficult to control the stability of surrounding rock in gob-side roadway under deeper mining depth and more complex stress environment. In the past decade, a series of new trends have emerged on excavation engineering in Shanghai, China. As available ground resources in congested urban areas are scarce, excavations become much larger and deeper than before. More excavations have to be carried out in close proximity to existing buildings, tunnels, utilities and other structures.
Underground space is a crucial strategic resource of China, a pivotal tool in alleviating "metropolitan diseases", a key carrier supporting green and low-carbon development, and a crucial breakthrough point for enhancing urban quality and propelling urban renewal. In recent years, China's deep oil and gas exploration and exploitation have developed rapidly. Technological advancements have played an important role in the rapid exploration and highly efficient development. China has abundant inland water resources, and the excavation of canals plays an important role in the development of transportation, water conservation, and flood control. In this chapter, the author will focus on the development of the canal system in China.
This study is based on China's DIG and explores its impact on regional mineral resource dependence (NRD) in 30 provinces of China. We find that, with a 1% increase in DIG, NRD declines by 7.6%, with a lag effect between the two. SYNOPSIS.
