The process of ore exploitation in opencast coal mining is complex and demands hiring many people and providing varied equipment. In order to provide continuous (twentyfour hours a day) production and to excavate the planned amount of ore and overburden in an opencast coal mine, it is necessary to achieve optimal working conditions.
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
