The main problems of these open-pit mines determine the implementation of the green mine plan. If you want to solve the pollution problem of the mine, please contact Hunan Ruisheng Mechanical and Electrical Equipment Co., Ltd. We focus on the construction of green mines!
With the increase in environmental protection supervision efforts and the introduction of the "National Industry Standard for Green Mine Construction", the country is integrating and closing down a number of small, scattered and disorderly mining enterprises to curb such enterprises, eliminating those that fail to meet environmental protection and quality standards and have poor safety conditions. At the same time, it is creating a number of green mines. So, how to solve the environmental protection problems during the construction of green mines? Here, we will introduce the environmental protection issues and solutions in the process of building green mines!

The final translation is as follows: > Open-pit mines mainly face the following four environmental protection issues, which are also the "enemies" of green mine construction:
1. Destruction of Land Resources
The damage caused by open-pit mining to land resources mainly lies in the construction of industrial areas in the mines, the stacking of coal gangue, road construction for mining, ground subsidence, and mining spoil removal, etc. The cumulative occupation of land by mines across the country amounts to 5.86 million hectares, and it has damaged about 1.06 million hectares of forests and 263,000 hectares of grassland. 。
2 Geological Disasters
The excavation of the ground and slopes affects the stability of mountains and slopes, causing deformation of the rock (soil) mass and triggering geological disasters such as collapses and landslides. The waste rocks (wastes) discharged by mines are often piled up on the slopes or in the valleys, and are prone to cause debris flows under the influence of heavy rain.
More than 60 landslides occurred at the Shencheng West Open-pit Coal Mine.
The landslide at Wanshan Quarry in Xiangfan resulted in 11 deaths.
The limestone mine of Panjiang Steel has experienced three major landslides, causing severe damage to the facilities.
On August 11, 2017, a slope collapse accident occurred at the Shangshun Coal Mine of Shanxi Coal Transportation and Marketing Group, resulting in 8 deaths.
3 Solid Waste Pollution
>
The final translation is as follows: > The cumulative stockpile of tailings and waste rocks in our country amounts to approximately 6 billion tons, among which 146 billion tons are stored as tailings and 438 billion tons as waste rocks. In the past five years, the annual discharge of tailings in our country has exceeded 1.5 billion tons, with non-metallic mines generating over 30 million tons of tailings annually.
4. Destruction of Water Environment System
The waste rocks and tailings from open-pit mines are exposed to the atmosphere. The sulfides in them undergo oxidation, turning precipitation into acid rain. Coupled with the non-compliant discharge of beneficiation and smelting wastewater, it often leads to the contamination of surface water bodies near the mining area, causing serious difficulties for irrigation of farmland and drinking water supply (ecological water supply) for livestock and humans.
Furthermore, the dewatering and drainage operations within the mine have altered the natural flow pattern of groundwater and the conditions for recharge and discharge, disrupting the balanced transformation among atmospheric precipitation, surface water, and groundwater.
The main problems of these open-pit mines have determined the implementation of the green mining plan. If you want to solve the pollution problem of the mines, please contact Hunan Ruisheng Mechanical and Electrical Equipment Co., Ltd. We specialize in the construction of green mines!
