In this study a loglinear model has been investigated to evaluate the role of various factors in coal mine injuries.  Data on the varieties namely age, safety performance, working condition, safety environment, management and supervision, emotional stability, job involvement, job satisfaction, and job stress have been collected through questionnaire survey.  The associations of the risk factors with occupational injuries are assessed through adjusted odds ratios (OR). The case study results reveal that significant contributing factors responsible for injuries are emotional stability (OR 2.36, 95% confidence interval (CI) 1.51-3.67), working condition (OR 2.14, 95% CI 1.37-3.35), safety performance (OR 2.04, 95% CI 1.30-3.17), safety environment (OR 1.96, 95% CI 1.25-3.06), and age with two ORs of 1.84 (95% CI 1.04 to 3.28), and 2.38 (95% CI 1.27 to 4.45). Identification of these risk factors of injuries will provide valuable information in injury preventive programs.
