Dynamic construction elevation determination method for mining while rehabilitating area

Abstract

The present invention relates to a dynamic construction elevation determination method for a mining while rehabilitating area, and belongs to the technical fields of mining technologies, land utilization and land reclamation. The method comprises: predicating dynamic subsidence in stages by using a probability integration method; considering an original elevation of the ground surface and stimulating a dynamic subsidence status of the ground surface in all stages; according to a local natural socio-economic situation, determining a reclamation elevation in the mining while rehabilitating area; considering a scope of a cultivated land in a mining while rehabilitating spatial layout and local water table buried depth and determining the scope of a cultivated land dynamic construction position; and finally, according to the reclamation elevation and ground surface subsequent subsidence, determining the dynamic construction elevation in the mining while rehabilitating area. In the method, a scope of the reclamation area, a situation of ground surface subsidence, the subsequent subsidence and the reclamation elevation are considered comprehensively during construction of mining while rehabilitating area, thereby determining the dynamic construction elevation in the mining while rehabilitating area. The method is easy to understand, easy to be used to guide project construction, and provides powerful support for field implementation of a mining while rehabilitating technology.

Description

technical field [0001] The invention belongs to the technical fields of mining technology, land utilization and land reclamation, and in particular relates to a method for determining the dynamic construction elevation of an inter-cultivated area during the construction process of mining while restoring engineering in a middle-high water level plain mining area. Background technique [0002] According to incomplete statistics, since the founding of New China, my country has mined about 44.5 billion tons of coal, which has made a huge contribution to social and economic development. However, coal mining has also brought many problems. 96% of my country's coal production comes from underground mining, and the roof is mostly managed by the longwall full collapse method. 91%. According to a conservative estimate, the accumulative subsidence area due to coal resource mining in my country exceeds 1 million hectares, and it increases at a rate of 30,000 to 47,000 hectares per year....

AI Technical Summary

Problems solved by technology

However, this method only determines the final reclamation space layout, and cannot guide the entire dynamic construction process well. Therefore, how to determine a certain The range of cultivated land that needs to be reclaimed at all times, as well as the construction elevation of the cultivated land, so as to better guide the construction of the project, is very important for the on-site implementation of the technical idea of ​​recovery while mining
