Treatment Efficiency And Soil Erosion In Shengli Coal Mine

While the development of mineral resources has brought huge economic benefits,it has also caused serious soil erosion.The prevention and monitoring of soil erosion in industrial and mining areas has always been the focus of people’s attention.Based on field monitoring data,this study conducted a comprehensive investigation on the effect of soil and water conservation in Shengli Coal Mine,focusing on the difference in soil erosion modulus of different soil erosion units and the amount of soil loss at different stages,and evaluated the effect of soil erosion control in Shengli Coal Mine.The main conclusions of the study:(1)The soil erosion modulus in the study area is mainly affected by rainfall,strong winds and human factors,but the human factors have the greatest impact on construction disturbances,leading to large differences in the intensity of soil erosion units.The construction of the project caused damage to the ground surface and increased soil erosion.Through the implementation of timely and effective treatment measures,soil erosion in the project area was controlled.(2)According to monitoring,the dynamic changes of soil loss during the construction period of the project are closely related to the construction disturbance.After the ground surface is disturbed,the soil erosion resistance capacity decreases.With the full start of the main works in each prevention zone,the surface disturbance area continues to increase.Large,the intensity of soil erosion increases,and the amount of soil erosion on the disturbed surface is increasing year by year.Therefore,during the construction period,excavation,filling,soil piling and other activities loosen the soil structure,which can easily cause new water and soil loss,which is the most serious period of water and soil loss.Therefore,good soil and water conservation measures during the construction period can effectively reduce the intensity of soil erosion.(3)The comprehensive management of soil and water conservation can fundamentally control soil erosion in the project area,restore surface vegetation,effectively control soil erosion,and significantly improve the ecological environment: the total area of soil erosion prevention and control is 278.09hm~2,and the disturbed land remediation rate 97.90%,the total soil erosion control rate reached 97.69%,the vegetation restoration rate is 97.41%,the forest and grass coverage rate reached26.48%,the slag retention rate reached 98.00%,the soil erosion control rate is 0.8,and the water and soil erosion phenomenon has been controlled in accordance with the state The standards have been significantly improved.
