초록

석탄 광산의 심부화 및 운행갱도의 증가로 인한 온도상승으로 작업환경이 점차 악화되는 광산에서 작업환경의 개선을 위하여 A광업소를 대상으로 통기평가를 하였으며 갱내의 통기 효율을 증가시키기 위하여 작업장의 온도 저하를 위한 선풍기 통기 방식에 대해 유동해석 프로그램을 이용하여 통기방식에 따른 운반갱도의 온도분포를 해석하였다. 연구결과 A 광업소의 소요환기량은 17,831 m3 min-1으로 산출되었으며, 실제 총 입기량은 16,474 m3 min-1로 환기량이 1,357 m3 min-1 부족한 것으로 나타났고 운반갱도에서 작업장까지의 온도는 송기식 통기보다 배기식 통기방식이 2~3℃ 낮게 분포하였다. 운반갱도에서 작업장까지의 길이가 긴 경우 송기식 보다는 배기식 통기방식을 운용 하는 것이 더욱 효과적일 것이다.

The working environment is deteriorated due to a rise in temperature of a coal mine caused by increase of its depth and carriage tunnels. To improve the environment, the temperature distribution resulted by using the fan type ventilation system aiming for the temperature drop is calculated by using a fluid dynamic analysis program. The analysis shows that A coal mine needs 6,152 m3 min-1 for in-flow ventilation rate but the total input air flowrate is 4,710 m3 min-1, 1,442 m3 min-1 of in-flow ventilation rate shortage and the temperature between the carriage tunnel openings and the workings with exhausting ventilation system type is 2~3 ℃ less than that with blowing ventilation system type. The exhausting ventilation system type would be more effective than blowing ventilation system when the distance between the carriage tunnel openings and the workings is relatively far.
