With the continuous improvement of social level, people gradually pay attention to environmental protection and maintain the ecological balance. However, there are some environmental pollution problems in the development of China's mining industry, which are not only unfavorable to the effective maintenance of the ecological balance, but also unfavorable to the healthy development of the mining industry.展开更多

文摘The environment, ecology and environment are the major issues that are widely concerned by all countries in the world. With the continuous improvement of social level, people gradually pay attention to environmental protection and maintain the ecological balance. However, there are some environmental pollution problems in the development of China's mining industry, which are not only unfavorable to the effective maintenance of the ecological balance, but also unfavorable to the healthy development of the mining industry.
