Abstract
Discusses selected problems associated with overburden removal in the Berezovo and Uryup mines of the Kansk-Achinsk coal basin. The overburden consists of sandstones, clays and aleurites with a moisture content of 15-24%. Hard inclusions (lens) 0.1-4.5 m thick and up to 50 m long consist of sandstones and aleurites. The overburden will be mined by heavy-duty bucket wheel excavators with a capacity from 5,250 to 12,500 m{sup 3}. Effects of moisture content in the overburden and hard lens on excavator operation and landslide hazard are analyzed. Schemes for overburden removal and oversize crushing recommended by 2 research institutes would result in increasing slope angle from 47-50 degrees to 70 degrees and cause a safety factor increase (1.6 times). 2 refs.
