Mining subsiding land environmental modification auxiliary decision information obtaining method

Abstract

A mining subsiding land environmental modification auxiliary decision information obtaining method comprises the following steps of obtaining, converting and superposing the mining subsiding land spatial data; butting the mine reserve data and directly obtaining the goaf data formed by the to-be-used reserves; carrying out the ultrasonic water depth detection on a sedimentation pools zone, real-timely acquiring the water weekly GNSS sedimentation automatic monitoring data and automatically superposing the spatial network points; carrying out the multilayer data analysis on the mining subsiding land data along a time axis; based on the mining subsiding land damage current situation and trend, obtaining the environmental modification auxiliary decision information. According to the present invention, by acquiring the basic data, such as the spatial dynamic data of the mining subsiding land, the mining data, etc., a mining subsiding land multi-dimension monitoring and prediction database is established, and a single-model uniform parameter conversion algorithm is adopted, thereby realizing the mining subsiding land environmental governance and land utilization economic analysis on the basis of one mathematical model, and providing the decision bases at the aspects of fund, technology and the like for the environmental governance of a mining subsiding area and the land recovery and utilization.

Description

technical field [0001] The invention relates to the technical field of environmental governance, in particular to a method for obtaining auxiliary decision-making information for environmental restoration of mining subsidence sites. Background technique [0002] After the mining of mine resources, the original stress balance state of the overlying strata in the goaf is destroyed, and movement and deformation such as caving, fracture, and bending will occur in sequence, and finally involve the surface, forming an approximately elliptical shape that is much larger than the goaf area. The subsidence basin is called the mining area subsidence. The subsidence of the mining area has the following hazards: the landform and ecological environment are severely damaged, the sustainable development of the economy and society is greatly restricted, ground fissures are formed at the edge of the subsidence area, and the cultivated land, traffic roads, communication lines, water conservanc...

AI Technical Summary

Problems solved by technology

In the auxiliary decision-making process for the environmental restoration of mining subsidence land, there is a lack of decision-making information, and thus a lack of decision-making basis for environmental governance and land restoration and utilization in mining subsidence areas, such as funding and technology, and reasonable governance cannot be carried out according to the actual situation of mining subsidence land. Restoration decisions, unable to effectively carry out ecological restoration, landscape restoration and cultivated land reclamation on mining subsidence land
