Abstract
The field investigation were planned and implemented in some of the coal mines at Central India. Based on the field investigations, the detailed parametric analysis was done with respect to sinkhole depth against each critical parameter. A sinkhole model has been developed by using statistical approach to understand the collective influence of all critical parameters and also to calculate sinkhole depth under different conditions.
