Abstract

Landslides in external waste dump(i.e. waste rock material dumped outside the quarry) of Tikak opencast coal project, North Eastern Coalfield(NEC), (located in north eastern part of India) is a major hindrance to sustain coal production of 0.6-0.7 million ton per annum from NEC. The external dump is standing against a hill slope of 8 degree inclination and the quarry operation is going on the other side of the hill (Fig1). The present height of the external dump is 80metre which is planned to be increased to 180m. The project is situated in seismic zone – V of Indian seismic map with basic horizontal seismic co-efficient of 0.08 and the vibration co-efficient in the dump due to blast vibration in the quarry is 0.06. This study discusses the methodology to tackle the above problem of Slope Stability of external dump which is planned for 180m.

Design of an External Waste Rock Dump in an Opencast Coal Mine Standing Against a Hill in Seismic Prone Area of India

San Diego, California

Landslides in external waste dump(i.e. waste rock material dumped outside the quarry) of Tikak opencast coal project, North Eastern Coalfield(NEC), (located in north eastern part of India) is a major hindrance to sustain coal production of 0.6-0.7 million ton per annum from NEC. The external dump is standing against a hill slope of 8 degree inclination and the quarry operation is going on the other side of the hill (Fig1). The present height of the external dump is 80metre which is planned to be increased to 180m. The project is situated in seismic zone – V of Indian seismic map with basic horizontal seismic co-efficient of 0.08 and the vibration co-efficient in the dump due to blast vibration in the quarry is 0.06. This study discusses the methodology to tackle the above problem of Slope Stability of external dump which is planned for 180m.
