Methodology: A cross-sectional study was conducted in 5 quarries of Kolar taluk, where blasting and quarrying of stone are carried out from July 2016 to September 2016. Quarry workers of either sex, aged >18 years, and above were included in the study. Results: In our study, 92 migrant workers were analyzed. Mean age of subjects 33.39 ± 10.54 years. In our study, 35.9% were smokers, 31.5% were alcoholics, 22.8% were using tobacco, and 6.5% were chewing beetle. Mean hours of occupation per day were 8.4 ± 1.9 h among stone crushers and 10.2 ± 2.1 h among non-stone crushing type of work. In our study, there was no significant difference in physical, psychological, social, and environmental domains of QoL between two groups of work. Environmental domain was lowest compared to other domains of QoL. Conclusion: Most common prevalent musculoskeletal problem was low back symptoms in 65.2%, followed by it was shoulder symptoms in 48.9% and knee symptoms in 46.7%.
