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] like figure 1 As shown, this embodiment provides a three-dimensional planning method for a green mine based on a three-dimensional real scene, including the following steps:

[0073] 3D modeling of 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 three-dimensional geographic information platform software, the original real-life model of the mine and the three-dimensional design model of mining mining are combined by partition and phase, and the mining model of the mine by partition and phase is obtained;

[0076] Integrate the greening design documents after mining with the mining model by zoning and staged mining to obtain a staged greening plan;

[0077] According to the phased greening plan, combined with the mapping relationship table of re-greening works a...

Embodiment 2

[0127] In the actual mining of the mine, the actual scope of mining may not be completely consistent with the pre-planned due to various engineering conditions or accidents. 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 discovered during the preliminary exploration was discovered, which needs to be bypassed. Through Example 1, a three-dimensional planning scheme for green mine mining can be obtained, but whether this scheme conforms to the actual situation still needs to be subsequently verified according to the actual mining situation of the mine.

[0128] In order to solve the above-mentioned technical problem, further optimize on the basis of embodiment 1, adopt following technical scheme:

[0129] In each mining stage of the mine, the UAV oblique photography technology is used to collect multi-view oblique images of the actual minin...

Abstract

The invention provides a three-dimensional planning method for a green mine based on a three-dimensional real scene, which includes the following steps: performing three-dimensional modeling on the original real scene of the mine; using computer-aided design software to convert the mine mining design file from two-dimensional to three-dimensional; Integrate the original real scene model of the mine with the 3D design model of the mine by division and stage; integrate the greening design file with the mine division and phase mining model; combine the mapping relationship table of the amount and cost of the regreening project to calculate the regreening project at each stage of the mine mining According to the mine regreening budget, judge whether the regreening project volume and cost of each stage of mine mining are reasonable; draw a three-dimensional planning plan for green mine mining. The invention can solve the technical problems that the virtual scene constructed by the virtual reality method is difficult to express the objective real scene, accurate quantitative analysis cannot be performed, and decision makers cannot accurately judge whether the mining planning scheme is suitable.

Description

technical field [0001] The invention relates to the technical field of mine development planning, in particular to a three-dimensional planning method for green mines based on a three-dimensional real scene. Background technique [0002] In recent years, the potential safety hazards and environmental damage caused by disorderly mining and illegal mining in mining areas have become increasingly prominent. The formulation and effective evaluation of reasonable mineral resource mining and post-mining ecological restoration plans will guide 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 integration, three-dimensional, intuitive and quantitative aspects 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 progress planning scheme of the...
