STUDY OF COMPOSITION AND MECHANICAL AND PHYSICAL PROPERTIES OF COAL-BEARING ROCKS IN THE MOKHOVSKOYE FIELD OF KUZBASS
V. E. Olkhovatenko, G. I. Trofimova
Studies were conducted to define mechanical and physical properties of coal-bearing rocks in the Mokhovskoye field of Kuzbass. Rock types distinguished in the section significantly differ in their stability of pit edges within the Mokhovskoye coal strip mine, the most stable rocks are represented by sandstones, unaffected by weathering. The stability of edges made up by weathered rocks depends on their condition, degree of weathering and fracturing, considerably reducing their strength characteristics.
Key words: Mokhovskoye field of Kuzbass, coals, stability of pit edges, strength characteristics of coalbearing deposits.
