Embodiment Construction

[0057] The implementation of the present invention will be further described in detail below in conjunction with an example of a mine working face.

[0058] According to attached Picture 1-1 First, the modeling principle of the embodiment is described:

[0059] Such as Picture 1-1 As shown, in the 3D lofting modeling of geological bodies such as coal seams and faults based on spline curves, the spline curve I is drawn by connecting the traverse points a, b, c, and d, and the spline curve II is drawn by connecting the traverse points e, f, g and h are connected and drawn, using the stakeout command, taking the exploration prediction sections 1, 2, 3, and 4 as the contours, using the spline curves I and II as the guide lines, and combined with the roof contour line III to carry out lofting modeling, that is Can produce coal seam three-dimensional model M and fault F. Figure 1-2 is a 3D model of coal seams and faults produced using simple extrude commands. Picture 1-1 and ...

Abstract

The invention discloses a spline based accurate predicating method for a face coal seam occurrence condition. The method is that a 3D geological information database of the coal seam face is built on the basis of the collected field construction data and according to the corresponding geological prospecting data; a geological prospecting profile map is created based on the 3D geological information database; a 3D mode of the face is built through stretching, cutting, lofting and other functional modules of the SolidWorks software according to the 3D geological information database, the geological prospecting profile map and top and bottom boards contour line prospecting data; a predication profile auxiliary plane is built in the 3D model of the coal seam face; the 3D model of the coal seam face is sectioned; the sectioning surface is subjected to accurate measuring and marking for the coal seam and fault geological data; the geological structure development rules such as the coal seam and fault of the coal seam face are analyzed according to the predication profile and used for guiding the actual production, and moreover, reference is provided for the production design adjusting and disaster prevention.

Description

technical field [0001] The invention belongs to the field of geological surveying and mapping, and in particular relates to a method for accurately predicting the coal seam occurrence in a working face. Background technique [0002] In recent years, 3D geological modeling has attracted widespread attention in the fields of geology, mining, and geotechnical engineering. The so-called 3D geological modeling is to use appropriate exploration data to generate a digital model with geological characteristics. Compared with the traditional two-dimensional data graphics, the three-dimensional model can express various geological phenomena more intuitively and accurately. At present, it is being paid more and more attention by experts, scholars and even front-line production and staff, and it has practical significance for coal mine production design. There have been a lot of research and exploration in 3D geological modeling at home and abroad. Scholars at home and abroad have pro...
