Underground mine planning is largely manual and can demand considerable resources to generate a working plan and to perform limited tests of sensitivity to variations in geological and mining conditions. It is possible to use computer aided mine planning to automate many of the manual procedures to allow the planner to evaluate a number of layouts, extraction strategies, and schedules. his paper examines the simulation and scheduling of an under- ground coal mine operation through the-use of on- screen graphics. The simulation will provide a basis for predicting productivity and other relevant information over a specified number of shifts. The software developed is extremely user friendly and reduces the tedium of repetitive manual calculations inherent to mine planning and drafting to a minimum, thus offering considerable savings in an area that is widely recognized as extremely labor intensive.
