Method for estimating exploitation and utilization actualities of underground spaces on basis of multiple urban geographic data

Abstract

The invention relates to a method for estimating exploitation and utilization actualities of underground spaces on basis of multiple urban geographic data. The method at least comprises the following steps of: obtaining a topographic map and a remote sensing map of an urban area and controlling drill hole information of each land mass; dividing meshes on the plane of the topographic map; arranging all the drilling hole information on a same reconnaissance controlling drill hole distribution map; projecting the arranged reconnaissance controlling drill hole distribution map to the topographic map; selecting whether to match the remote sensing map by combining the building type of a target land mass according to a drill hole quantity and drill hole depths, on the target land mass, of a reconnaissance controlling drill hole projection map, and determining an exploitation and utilization depth of an underground space; and calculating a resource quantity of the underground space according to the obtained exploited and utilized depth of the underground space. According to the method, the exploited and utilized depth of the underground space is distinguished by utilizing reconnaissance controlling drill holes, so that rapid and effective estimation is realized and the estimation result is high in correctness.

Description

technical field

[0001] The present invention relates to the technical field of geological survey, in particular to a method for estimating the status quo of underground space development and utilization based on a variety of urban geographic data, and a method and system for estimating the status quo of developed and utilized underground space by applying the estimation method to a computer . Background technique

[0002] Urban underground space refers to the space within the urban planning area and below the surface, with soil or rock as the main medium. As a resource, underground space has the concept of resource quantity, which refers to the development of three-dimensional space, including plane range and depth. According to the degree of development and utilization of underground space resources, underground space resources are divided into four categories: developed resources, undeveloped resources, partially exploitable resources and fully exploitable resources.
