Self-traverse evolution-based three-dimensional mining stress-pressure analysis method

Abstract

The invention provides a self-traverse evolution-based three-dimensional mining stress-pressure analysis method which is used for endowing an attribute class and a body structure class to a ground exploration spatial point so as to enable the ground exploration spatial point to carry out self-traverse to search for spatial difference value points of the same type of attribute class to be filled as geologic bodies of the same type. The method comprises the following steps of: (1) data acquisition; (2), geometry obtaining; (3) spline curve processing; and (4) data measurement and calculation processing. According to the self-traverse evolution-based three-dimensional mining stress-pressure analysis method, the design and management problems of water disaster prevention, gob arrangement and exploration process are solved by simulating the occurrence of new crushed zones and the change on rock mass structures caused by the engineering external force relation during mining engineering process, and a user can also endow other traverse attribute classes defined by self to established geologic bodies according to demands. The method has wide use and can be applied to fields such as geology, hydrology, mining and the like needing three-dimensional spatial analysis and resource management.

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
