Abstract

In recent years, as safety management in underground mines has become more important in the worldwide, mine safety management technologies combining information communication technology such as real-time worker position tracking, monitoring system and equipment remote control have been developed. Wireless communication system is mainly applied to these technologies for the flexibility of network configuration. There are some cases the monitoring system was installed in domestic underground mines, but, it is necessary to develop the technology more suitable for domestic mining standard. In this study, we developed the real-time environmental monitoring system using ZigBee technology and examined the result of application to domestic limestone mine. Furthermore, applicability of the developed environment monitoring system to $VentSim^{TM}$ LiveView was checked. This study is expected to contribute to the related studies like the optimization of the ventilation system in underground mines.

최근 전 세계적으로 지하 광산 내 안전관리의 중요성이 부각됨에 따라 실시간 작업자 위치추적, 모니터링 시스템, 원격 제어 등 정보통신기술을 접목한 광산안전관리 기술 개발이 한창 진행 중이다. 이러한 기술들은 네트워크 구축의 유연성을 위해 주로 무선 통신 방식이 적용되고 있으며, 국내에서도 지하 광산 내 무선 통신 네트워크를 통한 모니터링 시스템을 구축한 사례들이 있지만 국내 기준에 맞는 기술 개발이 필요한 실정이다. 따라서 본 연구에서는 지그비 기술을 활용하여 실시간 환경 모니터링 시스템을 개발하고 국내 석회석 광산에 적용한 결과를 고찰하였다. 나아가 개발된 환경 모니터링 시스템을 실시간 통기 모니터링 인터페이스인 $VentSim^{TM}$ LiveView와 연동하여 활용성을 검토하였다. 본 연구는 향후 통기 설비 제어 등 광산 통기 시스템 최적화에 관한 연구에 도움이 될 것으로 기대된다.
