Problems solved by technology

[0005] Aiming at the deficiencies in the existing technology, the present invention proposes a green mine stereo planning method based on three-dimensional real scene to solve the problem in the prior art that the virtual scene constructed by using the virtual reality method is difficult to express the objective real scene and cannot carry out Accurate quantitative analysis prevents decision makers from accurately judging whether the mining planning scheme is suitable for technical issues

Embodiment 1

[0072] Such as figure 1 As shown, the present embodiment provides a green mine three-dimensional planning method based on three-dimensional real scene, including the following steps:

[0073] Carry out three-dimensional modeling on the original real scene of the mine to obtain the original real scene model of the mine;

[0074] Use computer-aided design software to convert mining design documents from two-dimensional drawings to three-dimensional mining design models;

[0075] Using the 3D geographic information platform software, the original real scene model of the mine and the 3D design model of the mine are combined by division and stage to obtain the mine division and phase mining model;

[0076] Integrate the greening design documents after mine mining with the mining model of mine divisions and phases to obtain a phased greening plan;

[0077] According to the staged greening plan, combined with the mapping relationship table of the amount and cost of regreening, calc...

Embodiment 2

[0127] During the actual mining of the mine, due to various engineering conditions or accidents, the actual scope of mining is not completely consistent with the pre-planned. For example: after a landslide in a certain section of the mine, the section of the mountain can no longer be mined; or, during the mining process, an underground undercurrent that was not found during the preliminary exploration was discovered and needs to be bypassed. The three-dimensional planning scheme for green mine mining can be obtained through Example 1, but whether this scheme is in line with the actual situation needs to be followed up according to the actual mining situation of the mine.

[0128] In order to solve the above technical problems, further optimize on the basis of embodiment 1, take the following technical solutions:

[0129] At each mining stage of the mine, the UAV oblique photography technology is used to collect multi-angle oblique images of the real scene of the mining situati...

Abstract

The invention provides a three-dimensional planning method for a green mine based on a three-dimensional real scene. The method comprises the following steps of conducting three-dimensional modeling on an original real scene of the mine; converting two-dimensional mining design files into three-dimensional mining design files by computer-aided design software; using three-dimensional geographic information platform software to fuse the mine original live-action model and the mine exploitation three-dimensional design model in a partitioning and staging manner; fusing a greening design file with a mine zoning and staging mining model; in combination with the mapping relation table of re-greening project amount and the cost, calculating re-greening project amount and the cost of each stage of mining; according to the re-greening budget of the mine, judging whether the re-greening work amount and cost of each stage of mining are reasonable or not; and obtaining a three-dimensional planning scheme of the green mine. The technical problems that a virtual scene constructed by adopting a virtual reality method is difficult to express an objective real scene, accurate quantitative analysiscannot be carried out, and a decision maker cannot accurately judge whether a mining planning scheme is suitable or not can be solved.

Description

technical field [0001] The invention relates to the technical field of mine development planning, in particular to a three-dimensional green mine planning method based on a three-dimensional real scene. Background technique [0002] In recent years, the potential safety hazards caused by disorderly and illegal mining in mining areas have increased and environmental damage has become increasingly prominent. Formulating and effectively evaluating reasonable mineral resource mining and post-mining ecological restoration plans is crucial to guiding the construction of green mines and the orderly operation of mining areas. And the ecological restoration in the later stage of the mine is of great significance. The degree of integration, three-dimensionality, intuition, and quantification of the green mine planning scheme and the status quo of the mining area will play an important role in the effective evaluation of the planning scheme. When formulating the mining schedule plan o...
