At present, China has formulated relevant laws and regulations on mine ecological restoration, such as the Regulations on Mine Geological Environment Protection, which put forward clear requirements for mine environmental monitoring and supervision. In the process of mine ecological restoration, the local authorities are required to build a perfect geological environment monitoring system and monitoring network. , to carry out dynamic detection of geological environment, and take effective guiding measures. The mining right holder should also submit relevant monitoring reports regularly, so as to grasp the actual situation of mine ecology. However, in practice, although a series of policies and laws have been implemented, the implementation level is not ideal, and there are problems such as unresolved old accounts and increased new accounts for mine ecological restoration. Therefore, in mine ecological restoration, it is necessary to continuously strengthen supervision, ensure the effective implementation of various systems, and play its due role and effect.
(2) Problems in engineering field
Although China has carried out large-scale mine ecological restoration, there are some problems in practice, such as uneven construction team. Even some construction teams have an inaccurate understanding of the systematicness, completeness and scientificity of mine ecological restoration, which is affected by factors such as lack of professional knowledge, limited comprehensive technology and level. They unilaterally think that carrying out mine ecological restoration projects is actually digging and filling projects, such as covering exposed rocks with soil and filling collapsed pits. Due to the randomness of mine ecological restoration construction, restoration failure cases occur constantly, such as the good ecological environment in the first year of restoration and the gradual death of vegetation in the second year of restoration. Because the construction team didn't realize the significance of soil reconstruction in the mine ecological restoration project, it is easy to cause problems such as poor recycling effect among water, soil and vegetation, and when the vegetation is in a state of water shortage and malnutrition, it is bound to cause problems such as death. When plastic work such as dump and stope is carried out, the principle of natural landform is not introduced from a scientific point of view, which makes the ecological restoration of mines and natural environment ineffective and leads to increasing maintenance costs. Being in this state for a long time will inevitably lead to problems such as stability decline, soil erosion, and even landscape fragmentation. For example, in the treatment of acid waste mountain, there are some problems such as inaccurate fire extinguishing and unscientific fire prevention measures, which are easy to rekindle.
(c) Technology diffusion
In China, mine ecological restoration project has a long history of development. After in-depth research and exploration by a large number of scientific researchers, new ecological restoration technologies are constantly emerging. However, its popularization and application are limited by many factors, for example, the restoration project is mainly invested by the government, and the social investment is relatively small, so the funds are difficult to meet the restoration requirements. The use of new technology can effectively improve the repair effect, but the cost will continue to increase. For example, due to economic interests, the enthusiasm of construction enterprises to use new technologies is not high, which ultimately reduces the quality of mine ecological restoration projects.
