PDFAbstract: Metals together with coal are considered to be the base of the modern industry. Statistics show that together the mineral substances represent almost 20% from global raw material production. They are represented by fuels 12%, metallic ores 6% and nonmetallic minerals 2%. Mining industry is today in a transformation period. Economically, these transformations are impressive if we take into account mineral production variation or mining conditions. Coal is one of the most important fuels for electric power production in the world, but in the same time is the main source of acid rain and global climate warming. For modern society environmental protection is one of the most important problems if we consider the fact that economic development take place in this environment.
