Modifications Made to an Interactive Computer System for Evaluating Coal Mine Illumination.
NTIS: PB/81-236754 :27 pages
A computer system for 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 foot-candle levels incident on the mine surfaces. Shadowing effects of the machine are taken into account. The system operates, interactively from a tektronix 4014 graphics terminal that handles all input-output functions. The software is installed on a cyber 74 computer that communicates with the terminal by a telephone line. Several modifications to the system are described, the most important of which provides the ability to analyze surface mine lighting.
