Abstract

This study carried out the density and energy dispersive X-ray spectroscopy and particle size analysis which are the physical characteristics of coal dust by collecting samples of coal dust in the five domestic mines to control the coal dust through ventilation in the workplace for coal mining in the country. This will contribute to a more comfortable working environment by understanding the physical characteristics of the coal dust which is derived from any hard coal produced domestically. In particular, the result of PSA analysis showed that the size of coal dust sample for this study ranged from 0.007~88.614 μm were the particles less than 3.5 μm, the size range responsible for pneumoconiosis. To observe the flow of coal dust collected on the wind speed, the fallout of coal dust produced by the wind tunnel for the wind was measured and the particle size analysis of coal dust fallout was carried out. In addition, airborne dust is measured according to the mine velocity by using a multi-stage Anderson sampler in the mine where fine dust is generated in a large amount and the wind speed is found out to control the coal dust below 3.5 μm. In addition, natural ventilation pressure of A mine was calculated to prevent over design of the main fan.

석탄광산 분진을 환기로 제어하기 위해 현재 국내에서 가행되는 5개 광산의 석탄 분진 시료를 채취하여 석탄 분진의 특 성인 밀도와 원소분석, 입도 분석을 시행하였다. 이것은 국내에서 생산되는 모든 무연탄에서 파생되는 석탄 분진의 특성 을 이해함으로써 보다 쾌적한 작업환경을 제공하는 연구의 기초가 될 것이다. 입도분석(PSA)결과, 본 연구에 사용된 석 탄 분진 시료입자의 크기는 0.007∼ 88.614 μm 범위에 분포하였으며 이중 진폐증을 유발시킬 수 있는 3.5 μm 이하의 입 자가 광산 내 상당부분 존재하는 것으로 확인되었다. 5개광업소에서 채취한 석탄광 분진의 풍속에 의한 유동을 알아보 기 위해 풍동을 제작하여 풍속에 대한 석탄광 분진의 낙진을 측정하였으며, 낙진된 석탄 분진의 입도분석을 시행하였다. 또한, 실제 미세먼지가 다량으로 발생하는 채준 작업장에서 공기 중에 부유하는 미세먼지를 앤더슨 멀티스테이지 샘플 러(Anderson multi-stage sampler)를 이용하여 석탄광 분진을 작업장에서 환기되는 풍속에 따라 측정하였으며 3.5 μm 이하의 석탄 분진을 제어하는 풍속을 실험을 통하여 밝혀냈다. 주선풍기의 과설계를 방지하기 위해 A광업소의 자연환 기력을 계산하였다.
