THE USE OF TECHNOGENIC RAW MATERIALS FOR THE CONSTRUCTION OF THE SUBGRADE OF RAILWAY TRACK

Abstract

A comprehensive assessment of the rocks of mine dumps was carried out. The physical and mechanical properties of rocks as raw materials for the device of the roadbed of the access railway are investigated. Given the properties of the graded crushed stone and screenings from the crushing of mine rock. The possibility of using mine rocks instead of soil in the roadbed is substantiated. Features of hardening of the massif of a roadbed from mine breeds are shown. The technology of the device of an earthen cloth is stated. The successful operation of the access section of the railway track with a length of 27 km confirms the feasibility of using mine rocks for the construction of the roadbed. The use of rocks of mine dumps allows to solve some environmental problems: to reduce the number of quarries for the extraction of natural raw materials, to preserve the natural landscape of the earth’s surface, to free the land from the dumps, to reduce the pollution of water and air basins.
