Embodiment Construction

[0033] The method for creating a BIM-based coal seam GIM digital model of a coal mine working face in an embodiment of the present invention will be described in detail below. according to figure 1 The technical route shown is implemented.

[0034] Step 1: Use the underground coal seam roadway and rock layer roadway in the coal mine to conduct actual roadway measurement, and conduct multi-position, multi-angle, and multi-directional drilling methods to detect the occurrence of coal seams in the roadway of the proposed mining face; realize the detection of coal seam roadway roof floor drilling , and rock formation roadway penetration drilling detection.

[0035] The occurrence of coal seams or the use of underground precision geophysical equipment to detect the coal seams of the proposed mining face.

[0036] Step 2: Record the underground drilling construction ledger in detail, accurately record the drilling position, azimuth, inclination, drilling depth, coal penetration de...

Abstract

The invention provides a coal mine working face coal seam GIM digital model creation method based on BIM. The method includes: processing the field drilling actual measurement data; using a BIM modeling tool to edit three-dimensional geometric figure algorithm, creating a coal seam GIM digital model. The coal seam occurrence condition of the to-be-mined working face is accurately reflected; the technical defects of the existing two-dimensional CAD drawing technology are overcome; the problem that the coal seam occurrence condition cannot be visually and accurately checked before the coal mine is stoped on the working face is solved; the accuracy of coal mine production design management personnel for mastering the coal seam occurrence condition of the working face is improved, the coal yield of the working face is controlled more accurately, follow-up stoping work is guided to be carried out smoothly, and prevention and prejudgment on the disaster condition are achieved in advance.

Description

technical field [0001] The invention relates to a three-dimensional digital modeling method of a digital mine and a coal seam by using BIM technology, in particular to a method for creating a BIM-based coal seam GIM digital model of a coal mine working face. Background technique [0002] BIM is Building Information Modeling (Building Information Modeling), as a complete information carrier of construction projects, it is an innovative design, construction and management method. BIM is a three-dimensional "visualization" digital model based on three-dimensional digital design and engineering software realized by advanced computer technology. BIM has become an important technical means for the whole process management of projects in the construction field. Currently, it is mostly used in the construction of industrial squares in the field of coal mines. [0003] GIS technology (Geographic Information Systems, Geographic Information System) is a product of multiple disciplines...
