Computer Simulation for Evaluating Coal Mine Illumination Systems.
NTIS: PB 280 176 Available for Reference At Bureau Libraries :40 pages
A computer program calculating the illumination on coal mine surfaces due to machine-mounted lights is described. Utilizing numerical models of mining machinery and measured data on luminaire output characteristics, the program computes the ft-candle levels incident on the mine entry surfaces for any desired machine- luminaire-entry configuration. Shadowing effects of the machine are taken into account. Results are provided at 2-ft intervals on the face, left and right walls, floor, and roof. To provide a data base for these calculations, eleven 3-d machine models were prepared and the outputs of these luminaire types were measured. Calculations were done for 30 configurations.
