With the increase in environmental supervision efforts and; National Industry Standard for Green Mine Construction; The introduction of the policy is being implemented by the government to curb the situation by integrating and shutting down a batch of products; Small, scattered, disorderly&quo; Mining enterprises should eliminate enterprises that fail to meet environmental and quality standards, as well as those with poor safety conditions, while creating a batch of green mines. So how to solve the environmental protection problems in the construction process of green mines? Below, we will introduce the environmental protection issues and solutions in the process of building green mines< Br/>

The main problems faced by open-pit mines



Open pit mines mainly face the following four environmental issues, which are also important for the construction of green mines; Big Enemy:< Br/>


1. Land resource destruction



The destruction of land resources caused by Surface mine is mainly concentrated in the construction of the mine industrial square, gangue stacking, road construction, ground collapse and mine stripping. The cumulative land occupation of mines in China has reached 5.86 million hectares;, Destroying approximately 1.06 million hectares of forest;, Grassland: 263000 hm²< Br/>


2 Geological disasters



Ground and slope excavation affects the stability of mountains and slopes, leading to rock (soil) deformation and triggering geological disasters such as collapse and landslides. The waste rock (slag) discharged from the mine is often piled up on the hillside or in the valley, which is prone to debris flow induced by rainstorm< Br/>


More than 60 landslides occurred in the Fushun West Open Pit Mine< Br/>


A landslide at the Wanshan quarry in Xiangfan resulted in 11 deaths< Br/>


Three major landslides occurred in the limestone mine of Pangang, causing serious damage to facilities< Br/>


On August 11, 2017, a slope landslide accident occurred in the Heshun Coal Mine of Shanxi Coal Transportation and Sales Group, resulting in 8 deaths< Br/>


3 Solid waste pollution

&Nbsp;
nine hundred and one


During the ore processing process, a large amount of solid waste is generated, which is; Solid waste; Mainly including tailings, waste rock, coal gangue, and fly ash. Many mines dump solid waste at will, resulting in gullies and river siltation, poor flood discharge, and continuous flooding< Br/>


The cumulative storage of tailings and waste rocks in China is about 60 billion tons, including 14.6 billion tons of tailings and 43.8 billion tons of waste rocks. In the past five years, the annual discharge of tailings in China has reached over 1.5 billion tons, with non-metallic mines producing 30 million tons of tailings annually< Br/>


4. Water environment system damage
