Development a Questionnaire to Assess the Work Related Aaccidents in Open Pit Metal Mines According to Rules and Regulations

Several work related accidents occur in Open pit mines annually, resulting in permanent disability and death. The present study was designed to develop a measurement tool for assessment of incidents reported in Open Pit metal mines according to rules and regulations.

In this research, we first studied 200 cases of work-related accidents in the years 2009-2016, in order to provide the basic foundations for the formulation of the necessary elements for the structures of this questionnaire. The questionnaire was first designed with four structures, 13 dimensions and 81 questions. To assess the validity of the questionnaire, the formal, content, and structure validity of the questionnaire was used to determine the reliability of the two methods of internal consistency (Crohn’s Alpha) and test-retest using the coefficient of intratrail. Provided questionnaire was distributed among 377 employees of metal open-pit mines workers of Yazd and Kerman city. Data were analyzed through SPSS and LISREL software. Ethical considerations in this study were adhered based on the Helsinki guidelines.

The content validity of 22 items was eliminated and by calculating construct validity, a questionnaire with four constraints of violation of rules and regulations, unsafe operator behaviors, unsafe conditions of equipment and environmental unsafe conditions that has a reliability equal to 0.842, and the elements of the questionnaire has content validity. The scout study Cronbach’s alpha coefficient and KMO in the main study was 0.842 and 0.708 subsequently. Questionnaire items also have content validity (CVI = 0.84). The questionnaire data will only be used for analysis and will not be used elsewhere.

This questionnaire is an appropriate native tool with the approach of local role and regulations for assessing work-related accidents in open-pit metal mines
