The Study On Delimiting The Range Of The Subsidence Basin Of Mining Geo-Environmental Rehabilitation And Governance

The ground subsidence basin was formed by mine underground exploitation.We was commonly delimited the range of the ground subsidence basin by experience in the process of mine geo-environmental rehabilitation and government.This method of qualitative assessment is not reasonable.This topic research based on analysising and summarizing a large number of the project of mining geo-environmental protect and integrated renovation of examples.It explored the quantitative evaluation of delimiting the range of the ground subsidence basin by mine underground exploitation.This topic researched on using probability integral method to quantitatively evaluate the range of the ground subsidence basin and delimited the range of the ground subsidence basin of a coal mine in PingXiang City,Jiangxi Province.It's also delimited the range of the ground subsidence basin by experience.Through the analysis of the numerical of the range of the ground subsidence basin which is delimited by different methods above.It concluded that the probability integral method can effectively improve the prediction accuracy of delimiting the range of the ground subsidence basin,and its error is smaller.This topic has important guiding significance for guiding the mining environmental protection and recovery with smooth implementation.It aslo improved the quality of establishing the project of mining geo-environmental protection and integrated renovation.
