Study On Three-dimensional Visual Production Scheduling System Of Underground Tunnels And Key Technologies

Three-dimensional Visual Production Scheduling System of Intricate Underground Tunnels is a complicated system engineering. It contains not only realtime monitoring of the production operation, personnel and equipment distribution, but also wireless communication among people under mine and dispatchers on the ground. It also includes coordinating and management of each working unit's producation. This paper primarily focus on modeling and implementing of the crucial technology based on carefully research about the theories related. So it laies a good foundation to implement above-mentioned system.(1) Study on 3D spatial visualization of intricate laneway under mine.According to the data's feature of the laneway under mine, the topological relationship between three-dimensional data model and laneway is built. Based on dispersed data points of the laneway's cross-section, a algorithm on constructing intricate laneway model is put forword.
