Abstract

Subsidence is a depression of the ground on the surface due to extraction of minerals from underground. It occurs in two forms, namely, trough and pot-hole subsidence. Trough subsidence is a depression covering a large surface area whereas pot-hole subsidence is a localized phenomena occurring due to sudden collapse of overlying strata into the underground voids. It is extremely hazardous as it does not give any prior indication before its occurrence. In the study different conditions are considered like development & depillaring, presence & absence of faults and water bodies. This paper presents the results of the studies carried out in Indian mines representing different geo-mining conditions alongwith the pot-hole depth prediction multiple regression model developed. The developed model was validated for a few cases with the actual pot-hole depth measured.
