열적지표를 적용한 국내 고심도 석탄광산의 열환경 평가 연구 = A Study on Evaluation of Thermal Environment using Heat Stress Indices for Deep Coal Mine in Korea

국문 초록 (Abstract)

본 연구에서는 현장실측을 통하여 강원도 태백에 위치한 대규모 석탄광산의 열환경을 평가하였다. 열환경 평가를 위하여 WBGT, HSI, ESI, KATA지수 및 유효온도 등 다양한 열적지표를 적용하였고, 상관분석을 실시하였다. 분석결과 대부분의 작업장에서 높은 열환경이 평가되었고, 특히 열적지표 중 인체의 생리학적 특성을 반영하는 HSI와 최대 땀증발열의 상관계수는 –0.834이고 이것은 HSI지표에 가장 큰 영향을 미치는 것으로 나타났다. 최대 땀증발열에 가장 큰 영향을 미치는 인자는 공기속도이다. 따라서 운영 중인 제 1수직갱의 연장 굴착 또는 공기 누기를 방지하기 위한 구조물을 설치함으로써 환기량 증대를 통해 작업장의 열환경을 개선시킬 수 있을 것으로 판단된다.

다국어 초록 (Multilingual Abstract)

In this study, the thermal environment in a large scale coal mine located in Taebaek, Gangwondo was assessed by a field survey. In order to estimate the thermal environment, various heat stress indices such as WBGT, HSI, ESI, KATA index and effective temperature were investigated. Correlation analysis was also conducted. It was found that the thermal environment in most workplace was high. In particular, the correlation coefficient between HSI reflected in physiological fatigue characteristic and the maximum sweat evaporation heat was -0.834. This shows that the correlation coefficient have the most influence on HSI index. The factor which has the most influence on the maximum sweat evaporation heat is velocity of air. The thermal environment of high-depth coal mines is likely to be improved by installing a structure that enables the maximum prevention of extended digging, air doors, or the leakage of the inflow of air in the first shaft.
