This chapter discusses main areas of utilizing technogenic waste (burnt rocks of mine dumps and ash-slags). With this aim, there are stated assessment criteria for multilevel testing of waste according to the environmental requirements, chemical and mineral compositions, hydraulic activity, physical and mechanical properties, structural uniformity, formed volume in dumps, and economic indicators of their application. Based on certain examples, Russian and world experiences in the utilization of burnt rocks of mine dumps and ash-slags from the coal industry and heat power industry are considered.
