Test of Air Dust in the Mine Conditions during Operation of a Compact Dry Deduster Prototype

Abstract

In the article the problem of using an innovative solution for cleaning machines and equipment located in mining excavations using Underground Cleaning Technology (UCT) is concerned. During cleaning, an under pressure gas mixture, consisting mainly of carbon dioxide (dry ice), which sublimates and increases the cleaning efficiency, was fed. During the work, air dust from the presence of accumulation of coal and stone dust in the excavation and dust emissions from the cleaning process was created. The results of measurements of dust distribution at the workplace and its surroundings were presented in the article. The active methods to reduce air dust by a dry deduster were used during the cleaning process. The research of the air stream at the inlet and outlet of the deduster was covered. Based on the in situ measurements, the impact of the mining equipment cleaning method on the air condition in the excavation and the possibility of using UCT technology in underground mines was assessed.
