The Research On Safety Competence Model For Rock Blaster In Coal Mine

The blasting accidents with extensive magnitude and injury force have become the focus of safety production in coal mine. The competence can predict safety performance effectively, which can not only help the individual make self-understanding, and make use of the potential competence match to the post, but also provide a theoretical basis on recruitment and evaluation. The theses carry out empirical study following the logic thread"structure-evaluation-intervention". Taking special operators in coal mine as study subject, and combining with theoretical deduction and investigation interview, it puts forward correlated hypotheses. Use the method of cluster random sampling to obtain effective sample, and take SPSS15.0 & AMOS7.0 &Matlab7.0 as the tool for statistical analysis so as to test the theoretical models and build the competence evaluation system. The main conclusions are as follows:⑴Build the competence model for rock blaster. Based on literature review, opening interview, exploratory and confirmatory factor analysis, it found that rock blasters'competence mainly includes Sense of safety responsibility, emergency processing, emotional stability and blasting cognitive.⑵Build the competence evaluation system based on the effects of synergy and symbiotic. With the constructed Competence model, it identifies the specific content of competence assessment.Based on the model path coefficients normalized to determine the elements of each evaluation of the weight of a synergistic effect of all qualified method to calculate the dimension of the composite scores, using the symbiotic effect method find the maximum deviation dimension, then the actual competence scores to amend, the amended sum of scores obtained the final overall level of competence.⑶Proposed the blasting work safety management measures with the orientation of competency-based. For new employees and old employees adopt different management practices. Under the competence evaluation process, develop the targeted training mechanisms.
