A 3D modeling method of coal seam in working face based on geological data

Abstract

The invention provides a working face coal seam three-dimensional modeling method based on geological data. The method comprises the steps of measured geological data acquiring and coal seam model constructing. The first step comprises the step that after a working face transportation tunnel, a working face back air tunnel and a cut hole of a coal seam to be mined are tunnelled and constructed, the measured geological data of the coal seam to be mined are measured, wherein the measured geological data of the coal seam to be mined comprises the geological data of the coal seam, the geological data of a mining roadway and the geologic data of the cut hole. The second step comprises the steps of data storage 202, interpolation operation 202, three-dimensional coordinate database generation 203 and model constructing 204. Three-dimensional modeling software is called to establish the three-dimensional model of the coal seam to be mined. According to the invention, the method has the advantages of simple steps, reasonable design, convenient realization and good use effect; the three-dimensional modeling process of the working face coal seam can be quickly and easily acquired; and the three-dimensional model of the coal seam top is accurate, which provides reliable coal seam data for an automatic and intelligent comprehensive mining work face.

Description

technical field [0001] The invention relates to a modeling method, in particular to a three-dimensional modeling method of a coal seam in a working face based on geological data. Background technique [0002] In the process of coal mining, due to the complexity of the coal-rock interface, the problem of coal-rock identification has become a worldwide problem in automatic coal mining. In order to realize the identification of coal-rock interface, experts in the field of coal mining at home and abroad have carried out continuous exploration for more than 20 years, and have proposed more than 20 different identification methods. Among them, the most influential methods are: γ-ray method, Stress pick analysis method, radar detection method, infrared detection method, ultrasonic method, high-pressure water jet method, etc. However, due to the limitations of coal-rock interface identification technology, it is still not applicable in industry. At present, the method of combining ...
