IC 9418 Computer Graphics Simulations Comparing Reduced Exposure Mining Equipment-Shuttle Cars Versus Continuous Haulage Systems

The U.S. Bureau of Mines recently developed computer graphics simulations to characterize mining scenarios, specifically for room-and-pillar mining operations in a three-entry longwall development section. These simulations compare productivity between shuttle car and continuous haulage systems concepts. One of the continuous haulage systems concepts has bolting capabilities that supplement haulage function. Simulations showed the continuous haulage system to be more time efficient than the shuttle car system. Researchers can reuse the simulation code (e.g., mining rates and equipment capacities can be changed) should investigators care to compare production of other mining scenarios. computer simulation, found computer model modification flaws and mining scenario conceptual errors. The fundamental rationale for three-dimensional computer is to cheaply, easily, and quickly obtain information about operation and of a current or proposed mechanical coal or metal/nonmetal mining system. This report documents the computer graphics model and simulation developments and discusses some of the results and observations from the simulations.
