MODELLING AND CONTROL OF COAL QUARRY MINING USING VIRTUAL REALITY
Abstract
The technological process applied to coal opencast mines is based mainly on a continuous technology: an excavator, long-di stance belt transport and if need be, a spreader. These extensive systems are controll ed remotely from central control stations. For some purposes, the visualization of the technological process using SCADA/HMI systems is insufficient. On the basis of th is research, procedures for the creation of virtual models of technology, mining process and opencast mine were proposed. Virtual models are designed for the control of mining process, planning, modeling of safety and operating situations. For the control, mode ls can be interconnect ed with automated systems of technological units or their tec hnical models. Gradually individual parts of the technology were designed, interconnections were defined, and virtual models of technological units were created. The models were implemented in several environments and the result is a complete model including the opencast mine technology, surface and other objects. At interconnection to the geological and mining models of the opencast mine it is also possibl e to simulate a compre hensive situation in the opencast mine. In the artic le we describe procedures for virtual model design and solution.
