Abstract

This study introduces $M_{(i,j,k)}BCP$ (Mining Business Continuity Planning) which is the smart management system of mine disasters to achieve the safe and eco-friendly mining. Where, 'i' is mine kinds, 'j' is mining processes, and 'k' is risks at process respectively. By specifically setting 'i=1=limestone mine', this study also suggests that $M_{(i,j,k)}BCP$ is the smart management system of limestone mine. Mining risks used in this study were obtained from professional survey and literature review. This study classified these risks by five different mining processes and reduced risk numbers approximately 60 to 26. And they were all allocated into $M_{(i,j,k)}BCP$ and assessed. To do assess risks, this study used four risk indexes which are probability, casualty, facility loss, and discontinuity respectively. By the results of the assessment of risks, results could be four specific groups based on their causes and impacts. In addition, one of the results showed that the most possible risks at limestone mine was the roof-fall and rock-fall in digging process. This result means that $M_{(1,2,1)}BCP$ should be established as a first priority at limestone mine.

본 연구에서는 안전하고 친환경적인 광산관리를 위해 스마트 광산재난관리체계인 $M_{(i,j,k)}BCP$(Mining Business Continuity Planning)를 제안하였다. 여기서 'i'는 광산의 종류, 'j'는 광산의 업무공정, 그리고 'k'는 공정별 리스크 이다. 특히, 본 연구는 'i=1=석회석 광산'으로 규정하고 석회석광산의 재난관리체계를 $M_{(i,j,k)}BCP$로 제안하였다. 본 논문에 사용된 광산 리스크들은 문헌자료와 전문가 의견 분석을 통하여 얻었으며, 이러한 리스크들을 석회석 광산의 5대 공정에 맞도록 분류하여 그 수를 약 60개에서 26개로 줄였다. 줄여진 리스크들은 $M_{(i,j,k)}BCP$에 할당되고 평가되었다. 본 연구에서 리스크 평가에 사용한 척도는 1회 이상 발생빈도, 인명피해, 시설물피해, 업무중단시간 등 4가지이다. 리스크 평가 결과에 의하면, 리스크들은 4개의 특화된 군으로 분리될 수 있었다. 또한, 석회석 광산에서는 '채광 중 갱내 낙반 또는 붕락 발생 리스크'의 발생가능성과 위험도가 가장 높은 것으로 나타났다. 이 리스크에 대한 재난관리체계는 '$M_{(1,2,1)}BCP$'이다. 이는 석회석광산 개발시 $M_{(1,2,1)}BCP$가 최우선적으로 수립되어야 함을 의미한다.
