Research on mine laneway 3D modeling

Laneway is the artery of mine production, so establishing a true three-dimensional laneway model is important for guiding the mining design plans, project construction and security assistance and so on. This paper details the three-dimensional modeling process of laneway body, proposes the basic framework of building three-dimensional model as the laneway´s center line, according to the geometric spatial characteristics of laneway, and gives several control parameters of expressing the geometric shape on laneway. Meanwhile, taking the straight-line laneway as an example, through calculating the three-dimensional coordinates of laneway feature points, using space point, line and plane as the basic primitives, establishes the laneway´s three-dimensional surface model.
