The method comprises the steps: obtaining the type and section basic data of a target simulation roadway and the mining statistical data of a preset distance in the target simulation roadway; calculating the flatness of the target simulation roadway according to the mining statistical data, and generating fluctuation coordinate data conforming to normal distribution; obtaining an uneven curve conforming to normal distribution; establishing a roadway section contour line based on the roadway section basic data of the target simulation roadway; combining the uneven curve and the roadway section contour line, and obtaining an unevenclosed plane based on a roadway connecting line; conducting lofting in the roadway contour direction according to the uneven closed plane, and obtaining a solid model of the uneven roadway. Accordingto the method, the uneven curve of the roadway wall surface is generated by adopting normal distribution, the uneven form of the roadway wall surface can be well simulated by combining roadway sectionparameters, and the method can be used for sensor measurement calibration in a roadway and underground wind environment analysis.

Description

technical field [0001] The invention belongs to the technical field of mine engineering, and in particular relates to a three-dimensional modeling method, device and equipment for uneven roadways. Background technique [0002] Mine roadway is an important part of mine digitalization and intelligent platform construction, and it is also the main path for mine ventilation and human-machine work. The establishment of the roadway model is of great significance for the construction of smart mines and the scientific research of safety accidents such as underground ventilation, fire and emergency evacuation of personnel. The traditional roadway information is to use underground survey and data acquisition to draw two-dimensional cross-sectional diagrams and cross-sectional diagrams, which are fixed roadway shapes under a specific perspective. The roadway space state in the actual state needs to be judged by the personal experience and subjective consciousness of the technical staf...

Problems solved by technology

However, these two types of methods obtain the coordinate data of the roadway through measurement, and use the surface network connection to generate a 3D model of the smooth wall. simulation

Due to the complex underground environment, over-excavation and under-excavation usually occur during the roadway excavation process, which has a great impact on the accuracy of wind speed measurement, which is mainly based on single-point fixed measurement.

In the past, the roadway wind speed research and measurement calibration carried out by using smooth walls are all idealized numerical simulations, which have little reference significance for studying the actual situation in the mine.
