Usage of combustion metamorphic rocks in the building industry

Abstract

Geoecological problems arising during oil shale extraction and primary processing are investigated. Conditions of formation of refuse piles of combustion metamorphic rocks are covered. Evaluation of area and size of man-made formations of dumps and disposals of combustion metamorphic rocks formed during oil shale extraction at Syzran Oil Shale Processing Plant is conducted. Properties of combustion metamorphic rocks are studied and directions of their usage for production of building materials are determined. Principles of the local raw materials base formation on the basis of construction waste with inspection of dumps and disposals of producing and non-producing fields are applied. The prospects of formation of the raw materials base of the building industry with the use of technogenic raw materials from the dumps of Kashpir mine are determined. In order to decrease the areas taken by combustion metamorphic rocks and reduce ecological tension in the region, it is recommended to activate the usage of combustion metamorphic rocks in production of building materials.
