In order to increase the accuracy of rock blast-ability classification, the comprehensive evaluation model of rock blast-ability classification was established based on uncertainty measurement theory by eight factors including rock density, tensile strength, impact strength, integrity coefficient, compressive strength, sturdiness coefficient, wave impedance and explosive specific charge. The uncertainty measurement function was obtained based on the in-situ data; entropy theory was used to calculate the index weight of all indexes, and the comprehensive evaluation results of rock blast-ability classification were obtained using the rules of credible recognition criteria. In order to optimize the blasting design, the evaluation model was used to evaluate the rock blast-ability in Guiyang Chaoyangdong road engineering and the evaluation results fit in anecdotally with actual situation. Therefore, the evaluation model was a significant basis for promoting the blast effect.

Abstract


In order to increase the accuracy of rock blast-ability classification, the comprehensive evaluation model of rock blast-ability classification was established based on uncertainty measurement theory by eight factors including rock density, tensile strength, impact strength, integrity coefficient, compressive strength, sturdiness coefficient, wave impedance and explosive specific charge. The uncertainty measurement function was obtained based on the in-situ data; entropy theory was used to calculate the index weight of all indexes, and the comprehensive evaluation results of rock blast-ability classification were obtained using the rules of credible recognition criteria. In order to optimize the blasting design, the evaluation model was used to evaluate the rock blast-ability in Guiyang Chaoyangdong road engineering and the evaluation results fit in anecdotally with actual situation. Therefore, the evaluation model was a significant basis for promoting the blast effect.
