Abstract

Almost all large capacity equipment in local underground limestone mines are equipped with diesel engines and this dieselization trend is accelerating. Even though the dieselization also hike the possibility of mine fire break-out, there is no safety and disaster prevention measures. This study aims at analyzing the fire smoke propagation and hot gas stream generated from a 25-ton diesel truck fire in the working face and adjacent haulage ways. The ultimate goal is to seek for the safety measures including mine ventilation in order to secure the safe evacuation system for mine workers and protection measures for the mine equipment.

국내 지하 석회석 광산의 거의 모든 대형 채굴 및 운반 장비들이 디젤화 되고 있어 이로 인한 화재발생 가능성은 점진적으로 커지고 있으나 이에 대한 안전 및 방재대책은 전무한 실정이다. 본 논문에서는 주방식 채굴법을 적용하는 석회석 광산 채굴막장에서 대형 25톤 운반트럭 화재발생시 맹갱도 형태의 채굴막장과 주변 대단면 운반갱도내에서의 화재연 확산 및 고온 유해가스층 확산을 CFD 분석함으로써 화재원 인접공간내 작업원의 대피 및 시설물의 피해 가능성을 검토하고 궁극적으로는 대피방안 마련과 환기시스템 제어를 위한 기초 자료를 제공함을 목적으로 한다.
