Abstract

In this study, ZigBee-based low-cost and low-power modules, using accelerometer and dust sensor, were developed to monitor vibration and dust density in underground mines. At the Taeyoung EMC's Samdo mine in Dogye-eup, Samcheok-si, Gangwon-do, 19 vibration modules, 9 dust modules, and 6 additional router modules, were installed. The values of vibration and dust density, before and after blasting, were obtained from the coordinator module. As a result, it was possible to establish a wireless sensor network in an underground mine. The vibration at the time of blasting was detected and the change in dust density, before and after blasting, was monitored. To solve the problem of unstable network connection in some modules, changes in module settings and line of sight analysis were required. This study is expected to be a basic research towards realizing a safe environment in relatively small underground mines with harsh conditions.

본 연구에서는 ZigBee 무선통신기술과 가속도 센서, 미세먼지 센서를 사용하여 저비용·저전력의 모듈을 개발하고 지하광산 내 진동 및 분진 밀도를 모니터링하였다. 강원도 삼척시 도계읍에 위치한 태영EMC 삼도사업소를 대상으로 19개의 진동 측정 모듈과 9개의 분진 측정 모듈, 6개의 추가 라우터 모듈을 설치하였고, 코디네이터 모듈에서 발파 전후의 진동 값과 분진 밀도를 취득하였다. 그 결과 지하광산 내에서도 무선 센서 네트워크 구축이 가능하였고, 발파 시점의 진동을 감지하고 발파 전후의 분진 밀도 변화를 모니터링할 수 있었다. 일부 모듈에서 네트워크 연결이 불안정한 문제를 개선하기 위해서는 모듈 설정의 변경, 가시선 분석 등이 필요한 것으로 분석되었다. 본 연구는 영세하고 열악한 지하광산에 적용되어 더욱 안전한 환경을 위한 기초 연구로써 활용될 수 있을 것이다.
