Significance of Logistic Regression Modeling in Open Cast Mine Injury Investigations

The paper significance of logistic regression modeling in opencast mine injury investigation addresses the problem of open cast mines and related modeling through the application of multivariate analysis. The epidemiological methods developed in this work will assist the safety management to identify significant risk factors and the risk groups which can provide a basis to develop prevention strategies including training. The findings of the multivariate statistical analyses indicate that both the personal and impersonal factors affect the occurrence of an injury. In this study although 8 risk factors were suspected, The findings are of two types: variables that show distinct relationship with the degree of injury and those, whose significance lies in the fact that they do not show any relationship with the degree of injury. Of the former, are personal factors, environmental condition, machinery condition, job satisfaction and risk taking behavior that are significance. The adjusted odds ratios are 12.17, 5.26, 6.35, 5.04 and 9.85 respectively for significant risk factors in relation to injury vs no injury case. Similarly, 9.54, 8.40, 4.86 and 9.28 respectively for reportable vs no injury case. On the basis of ordinal logistic regression results, we see that for one unit increase in personal factors, environmental condition, job satisfaction and risk taking behaviors, there are respectively 1.554, 1.243, 1.440 and 1.613 units increase in log odds of injury. accident–prevention programs must identify reasons for unsafe conditions and/or behaviors and need to redesign the work environment and/or unsafe behaviors. Mine management and employee’s commitment are vital in achieving good health and safety performance. Dumper systems and tires must be properly maintained. Dumper cabs must be kept free of loose items, such as cleaning rags, or empty oil cans that create distractions and footing hazards. Decks must be kept clean of slippery oils, tools, and spilled muck. Dumper accessories, such as radios, mirrors and safety strobes, must be kept in proper working order. Dumper drivers should use seat belts during driving.
