This study assessed heart rate during work and recovery of 20 male coalminers working underground as shovelers, working in haulage. While extraction is going on they are susceptible to a high degree of physical stress which varies according to the nature of their work. Since coal production is highly correlated with the efficiency of their work, an attempt has been made to evaluate their job stress and recovery patterns during their working schedule. The exaggerated workload arising out of self-paced hard work fosters insufficient recovery which accentuates fatigue and brings about a gradual decline in overall performance. Consequently, this job-specific study was undertaken to evaluate the nature of this specific activity, along with the recovery trend of the workers.
