摘要

A computer program 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 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 three luminaire types were measured. Calculations were done for 30configurations.
