Abstract
Abstract In order to comply with the provisions of the normative acts in the field of air quality (STAS 12574/1987 - maximum allowed concentrations of sedimentable powders [1]), it was proposed to build a water mist dedusting facility within the coal deposit to stop the dust emissions at the source. The installation must ensure long-term operation in harsh conditions, with resistance to wear and minimal maintenance: operating time 12-14 hours/day, 365 days/year. The dedusting plant is composed of the water house, the distribution network, the fog production plants and the electricity supply plant. The process used to create the mist is based on the use of high pressure pumps. The equipment consists of fog guns equipped with high-pressure water spray nozzles and dispersion fans that are purchased fully equipped including a remote control installation; 6 spray guns were provided.
