INTENSIFICATION OF CONSTRUCTION RAW MATERIALS EXTRACTION AND BUILDING MATERIALS PRODUCTION FOR RESTORATION OF UKRAINIAN INFRASTRUCTURE

Abstract

The losses of Ukraine’s economy from damage to physical infrastructure since the beginning of hostilities already amount to more than $ 100 billion. This situation will lead to the need to increase the raw materials extraction and building materials production to restore the infrastructure of Ukraine in the postwar period. A comprehensive approach to the raw materials extraction and building materials production has been developed. It includes three areas.Direction 1 – increase in production capacity of mining and processing plants without compromising on influence to the environment (improvement of extraction technology or transition to resourcesaving (waste-free) extraction technologies, modernization of machinery and equipment). Direction 2 – development of technogenic deposits. Direction 3 – utilization of construction waste generated as a result of the war. Direction 1 can be implemented through the introduction of resource-saving mining technologies, for example,cyclic-current technology of crushed stone production, which consists in the use of modern gyro crusher located on two paired ledges in the quarry area and combining it with a steep conveyor, which will reduce the amount of intermediate transport equipment and increase quarry productivity. It can also be implemented by improving technological parameters, for example, the use of resource-saving and environmentally friendly design of charge and stemming, which together can reduce mineral losses and completely neutralizeharmful gases during the explosive destruction of the rock. In the second direction it is proposed to develop technogenic deposits, to involve for the production of fiberglass, dyes and other building materials wastes from the processing of construction raw materials. It will allow to intensify the use of already extracted natural raw materials and receive additional income from its deeper processing to obtain new products. In the conditions of growing demand for construction raw materials and the need to dismantle the post-wardestroyed infrastructure facilities of Ukraine the re-involvement of construction materials in construction and other industries after their separation and, if necessary, processing is proposed under the third direction. This will reduce the burden on the mining industry, and in turn on the environment.
