Graphical Simulation of Continuous Miner Production Systems

A Simulation/Animation Model (SAM) with several unique features has been developed for continuous mining in room-and-pillar production systems. Initial cut data are generated by the program based on a short list of general section parameters, and is graphically displayed on the screen for checking and editing. This portion of the program includes several intelligent features. For example, a different cut sequence will be generated for uni-directional section ventilation than for bi-directional flow. Once the data are accepted, the entire simulation may be viewed in animation. Effectively, much of the data are checked visually by watching the actions of the mining equipment. Following the simulation, results are summarized as bar and pie charts, as well as printed output. In addition to the extensive use of graphics, the program contains several advances in simulation techniques as well.
