Abstract

The invention provides a coal face coal seam three-dimensional display method based on geologic body modeling and an application thereof, solving the problem that three-dimensional coal seam space occurrence parameter changes cannot be visually and effectively obtained in real time in the ultra-thick coal seam working face automatic mining process. The coal face coal seam three-dimensional displaymethod comprises the steps: using autoCAD software to process the drilling histogram at different positions of the upper crossheading and the lower crossheading of the coal face; establishing a coalseam roof elevation line and a coal seam floor elevation line, extracting relative coordinates of elevation control points on the coal seam roof elevation line and the coal seam floor elevation line,performing interpolation homogenization processing on the elevation control points by utilizing geological modeling SUFER software, generating a three-dimensional geological geometry of the coal seamworking face by virtue of ANSYS software; and performing three-dimensional display by virtue of CDEM software. According to the coal face coal seam three-dimensional display method, the extra-thick coal seam three-dimensional numerical model of the fully mechanized caving face can be quickly and accurately generated, and the extra-thick coal stratum three-dimensional structure is conveniently displayed, and coal seam occurrence data at any advancing position of the working face are obtained in real time, and real-time and accurate geological reference data are provided for dynamically adjusting extra-thick coal seam automatic coal caving control parameters.

Technical field [0001] The invention relates to the technical field of coal seam numerical modeling, in particular to a three-dimensional display method of coal mining face coal seam based on geological body modeling and its application, which realizes the modeling and display of the three-dimensional structure of the coal seam of the working face and solves the thickness and inclination of the coal seam. Background technique [0002] The safe and efficient production of the fully mechanized top coal caving face of the extra-thick coal seam largely depends on the geological conditions of the extra-thick seam face. The existence of the top coal of the extra-thick seam has an impact on the mining method and production benefits of the entire mine. Will have a major impact. The thickness of the coal seam affects the design method of top coal caving. For example, the setting of caving ratio affects the design and selection of hydraulic supports in terms of supporting height; the thick...

[0005] In view of the fact that the existing methods cannot intuitively and effectively know the change of the coal seam floor elevation, the change of the thickness of the coal seam, the change of the dip angle of the coal seam, the change of the dip angle of the coal seam and the Geological occurrence conditions such as gangue occurrence in coal seams cannot effectively provide real-time coal seam geological occurrence data for the determination of control parameters for automatic mining of extra-thick coal seams. The present invention proposes a three-dimensional modeling of extra-thick coal seams And the dynamic display method of the 3D model, as well as the calculation method of calculating the thickness of the coal seam and the inclination angle of the coal seam at any advancing position in the working face of the extra-thick coal seam, can correctly guide the mining and discharging of coal in the mine, adjust the coal mining process in a timely manner, and obtain the thickness and depth of the automatic mining coal seam dynamically in real time The inclination angle and the distribution of gangue have important guiding significance for determining and dynamically adjusting the control parameters of automatic mining equipment, which improves the safe and efficient production of mines
