overburden in opencast mines. Abstract Opencast mining operations involve huge quantities of overburden removal dumping and backfilling in excavated areas A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also given rise to danger of dump failures
STABILITY ANALYSIS OF OVERBURDEN INTERNAL DUMP .
Overburden dumps in opencast coal mining operation experiences two types of failure surfaces (Hebil, 1986) [4]: Circular failure surface Circularcumplanar failure surface (Cambell, 1986) [5].
