Abstract

To ensure the safety of workers inside mines, it is important to remove dust particles generated within tunnels. Although filter-type dust collectors are commonly used for dust removal, they are likely to experience filter clogging, leading to a reduction in their dust removal efficiency over time. Especially in mines of non-metallic resources, dust tends to combine with moisture within tunnels, resulting in easy clogging of filters and making operation of the dust collector difficult. To address this issue, a mine-specific vortex-type scrubber was developed to eliminate filter clogging and reduce dust, thereby enhancing workplace safety. This technical report introduces the design, analysis, fabrication, and testing involved in the development of mine-specific dust collectors.

광산내 작업자의 안전을 확보하기 위해서는 갱도 내 발생하는 분진의 제거는 중요하다. 분진제거를 위해서 필터형 집진기를 많이 사용하지만, 필터 막힘 현상이 있어, 시간에 따라 분진 제거 효율이 감소한다. 특히 석회석 같은 비금속 광산에서는 분진이 갱도내 습기와 결합하여 필터를 쉽게 막히게 하여 집진기의 운용을 어렵게 한다. 이에 광산용 와류형 세정식 집진기를 개발하여 필터막힘 현상을 없애고 분진을 감소시켜 작업안전을 확보하고자 하였다. 이 기술 보고에서는 광산용 집진기의 개발을 위해 설계, 분석, 제작 및 시험을 소개하였다.
