Abstract

Drilling accuracy is known to be one of the most important factors determining blasting efficiency in mining by blast operation. Therefore analysing the causes of drilling error and preparing a countermeasure for minimizing drilling error are very important for blasting efficiency and safety. In this study, causes of drilling error are analyzed with dividing them into controllable factors and uncontrollable factors, and relationship between each cause is also comprehended through field measurement and AHP analysis. Finally, effective measures to help lower the drilling error are proposed with the results from weighting analysis for each factor.

발파를 이용한 채광작업에 있어서 천공의 정확성은 발파의 효율성을 결정할 수 있는 중요한 요소 중의 하나이며, 따라서 천공오차의 발생 원인에 대한 분석과 천공오차의 발생 정도를 줄일 수 있는 대책 마련은 발파의 효율성 및 안전성 확보에서 매우 중요하다. 본 연구에서는 천공오차의 발생 원인을 제어가능 요인과 제어불가능 요인으로 나누어 분석하였으며 현장조사와 AHP 분석을 통하여 천공오차를 유발하는 요인들의 영향성을 살펴보았다. 또한 이들 간의 가중치 분석을 통해 천공오차를 낮출 수 있는 효과적인 대책을 제시하였다.
