Abstract

This paper deals with the investigation in a coal mine where only development work was in progress. Strain measurements were carried out in the side of the pillars, as the galleries were advanced. The maximum strain developed was noticed up to 100 m from the headings. The maximum strain developed was 3 mm/m. In the majority of cases it was below 0.5 mm/m. The magnitude of strains were found to increase and decrease.
