mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines [3]. In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
In this paper, several techniques considered for mining and processing the regolith on the lunar surface are presented. These techniques have been proposed and evaluated based primarily on the following criteria: (1) mining operations should be relatively simple; (2) procedures of mineral processing should be few and relatively easy; (3) transferring tonnages of regolith on the Moon should be ...
Surface mining is the predominant exploitation method worldwide In the USA, surface mining contributes about 85% of all minerals exploitation (excluding petroleum and natural gas). Almost all metallic ore (98%) and non-metallic ore (97%), and 61% of the coal is mined using surface methods in the USA (Hartman and Mutmansky, 2002).
