Coal mine tunnel modeling method based on three-dimensional geologic body

Abstract

The invention relates to the technical field of geological modeling, in particular to a coal mine tunnel modeling method based on a three-dimensional geologic body, which comprises the following steps: a single well model construction step: acquiring logging data, performing well position restoration according to the logging data, and generating logging model data according to the logging data; a multi-well connection step: acquiring a stratigraphic sequence framework, and generating a geologic body model according to the stratigraphic sequence framework and the logging model data; a roadway construction step: obtaining roadway node coordinates, and generating a roadway model according to the roadway node coordinates; and a mine laneway combination step: generating a mine laneway model according to the geologic body model and the laneway model. The data of the mine laneway can be reflected more comprehensively and truly, so that the effect of three-dimensional laneway modeling in practice is improved.

Description

technical field [0001] The invention relates to the technical field of geological modeling, in particular to a coal mine roadway modeling method based on a three-dimensional geological body. Background technique [0002] The rapid development of digital technology, information technology and computer technology has pushed human life into a new stage of intelligence. The coal mine field has also begun to transform and upgrade, and is constantly developing towards intelligent construction. For the intelligent construction of the coal mine field, the model construction of the mine roadway is a basic and core step. [0003] The Chinese patent with publication number: CN110363844A discloses a method and system for three-dimensional modeling of coal mine roadway. First of all, use GPS positioning equipment to obtain the latitude and longitude coordinates of each key part of each roadway in the coal mine; and convert it to the world coordinate system; then, measure the cross-secti...

Problems solved by technology

[0004] The above-mentioned invention patent models the roadway according to the coordinates of the roadway, reflecting the spatial topological relationship of the mine roadway, but because it only models the roadway itself, The interaction between the roadway and the environment in the three-dimensional geological body is ignored, and the roadway and the geological body environment are an inseparable whole in the actual production process, so the roadway model established by this method cannot be comprehensive and true. It reflects the data of mine roadway, so for coal mine construction, production and emergency rescue, the practical effect of this type of 3D roadway modeling is relatively low
