Three-dimensional mining stress analysis method based on self-traversal evolution

Abstract

The present invention provides a three-dimensional mining stress analysis based on self-traversal evolution by assigning attribute classes and body structure classes to geodesic exploration space points, allowing them to self-traverse to find spatial difference points of the same attribute class to fill in similar geological bodies The method includes the following steps: (1) data collection; (2) geometry construction; (3) spline curve processing; (4) data calculation processing. The three-dimensional mining stress analysis method based on self-traversal evolution of the present invention can make good use of the engineering external force relationship in the mining engineering process to simulate the generation of new broken zones and changes in coal and rock mass structures to solve the problem of avoiding water damage and goafs. For the design management of layout and mining technology, users can also assign other traversal attribute classes defined by themselves to the established geological bodies according to their needs. The method has a wide range of applications and can be applied to fields requiring three-dimensional space analysis and resource management, such as geology, hydrology, and mineral resources.

Description

technical field [0001] The invention relates to a mining stress analysis method, in particular to a three-dimensional mining stress analysis method based on self-traversal evolution. Background technique [0002] At present, microseismic microwave detectors are usually used to manage the pressure on the roof of the coal seam to control the sudden gushing of gas, and there is no analysis model device to predict and avoid management in advance. [0003] Digital mining is an emerging technology. There are also digital mining products on the market. This type of product performs triangulation surface modeling through the data of geological survey and exploration points, and stitches two surfaces to form a volume model. This type of product has the following types: Point defect: [0004] 1. The data of the exploration point is not real, the data between the exploration points is calculated, and the edge of the model is not real; [0005] 2. The description of the geological bod...

Problems solved by technology

[0004] 1. The data of the exploration point is not real, the data between the exploration points is calculated, and the edge of the model is not real;

[0005] 2. The description of the geological body is only through the surface data, and the value cannot be assigned in the geological body. With the increase of mining activities, the geological body has begun to be gradually changed. The model with the real point is split and can only represent the shape of the volume model. have display significance;

[0006] 3. The mining process simulation can only conduct quantitative analysis according to advance customization, describe the mining time process, and cannot qualitatively analyze other issues
