Ecological Systems and Devices Annotation << Back TECHNICAL AND ENVIRONMENTAL ASPECTS OF THE DEVELOPMENT OF GEOTECHNOLOGIES WITH SELECTIVE EXCAVATION OF MINERALS Yu.P. Galchenko Current trends in the greening of technological progress in all fi elds led to the formation in the mining industry of new scientifi c and technical direction on the creation of «green» geotechnologies with a minimal amount of solid waste on the earth’s surface. The most signifi cant prospects here is the development of the ideas of the election of the minerals extraction. The methodological basis of this direction is the principle of matching levels of selectivity of the technology to the level and nature of variability of the natural distribution of useful component within the studied section of the lithosphere. During the recess of the reserves of ore bodies with areal uneven nature of the mineralization value of this index and the position of the ore areas are projected according to the sampling excavation and fans fender wells. Used the indicator of technological ore content of the ore body takes into account not only geologically the specifi ed content and size of the ore areas, but also the capabilities of the technology used to isolate those sections in the process of breaking ore. During mining thin ore bodies, the principle of distinction recesses is realized at the expense of purposeful use of the energy of the explosion or for selective crushing, or garbage mixed ore and rock beats part of the array. Environmental consequences of the use of geotechnologies to the election recess are expressed in multiple reduction in solid waste, placed in the limits of land allotment of mining companies.
