Simulation Study on Hydrological Process of Soil
Coal mining has driven the local economy, but it has also seriously damaged local production and the living environment [1,2].The environmental damage caused by large-scale, open-pit coal mining is Open-pit mining. Some 53% of South Africa’s coal is produced from surface mining, via open-cast or open-pit mines. This is because the coal is less than 60 metres below the surface.

Analysis of Plant and Soil Restoration Process and Degree of
Vegetation and soil restoration are the key to ecological reconstruction in the damaged areas of open-pit coal mining areas. Ecological stability is an important indicator of the degree of ecological restoration. In this study, the ecological stability and the process of plant and soil restoration were investigated at different refuse dumps in three However, the level of eco-environmental destruction in open-pit mining regions is ten times higher than in other mining areas (Zhou et al., 2018). According to statistics in 2018, China has 67,700 mines with an annual mining capacity of more than 30 billion tons, which destroy over 4 million hectares of land, and tailings waste rock Green and climate-smart mining: A framework to analyze open-pit

Impact of Coal Mining on the Moisture Movement in a Vadose Zone in Open
Long-term dewatering of groundwater is a necessary operation for mining safety in open-pit coal mines, as extensive dewatering might cause ecological problems due to dramatic changes in moisture movement in the soil, especially in ecologically fragile areas. In order to evaluate the impact of the coal mining operation on moisture 12.10: Open-Pit Mining. Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.

At present, the open-pit coal production of China ranks second in the world (Wang Citation 2014) and is developing toward a large-scale direction.It has been proven that large-scale open-pit coal fields are concentrated in Xinjiang, Inner Mongolia, and other ecologically vulnerable areas (Jiskani et al. Citation 2021).Green mining is the theme of coal mining The intelligent construction of open-pit coal mines is still in its initial stage. The automation of equipment, design, and management information does not meet the requirements of intelligent mining. Therefore, the intelligent transformation, upgrading, and development of open-pit coal mines is an urgent and difficult task.Research and practice of intelligent coal mine technology

Coal mining has driven the local economy, but it has also seriously damaged local production and the living environment [1,2].The environmental damage caused by large-scale, open-pit coal mining is particularly serious, which causes geological disasters to occur frequently [].The dump site is a giant, artificial, unconsolidated The lump rate in the original blasting process is normally around 10%. Since the minimum width of the electric shovel mainly used in the Pingshuo East Open-pit Mine is 2 m, it is stipulated that the rock lumpiness that is greater than 200 cm after blasting is a big lump, and manual registration is adopted.Open-Pit Mine Geological Model Construction and

Assessing the effect, attribution, and potential of vegetation
1. Introduction. Coal stands as one of the most crucial fossil fuels, which has made outstanding contributions to the national economies of numerous countries (Thakur et al., 2021, Zhu et al., 2021).Open-pit mining has been steadily increasing worldwide due to the advantages of better safety and higher mining rate over Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.Open-Pit Mining Method and Process Epiroc
