ABSTRACT: Prolonged exposure to coal dust leads to various lung disorders,
including incurable coal workers’
pneumoconiosis (CWP), and endangers miners’ health in underground mines.
This article summarizes the latest research progress in dust control technology, including chemical dust suppressants, foam dust removal, ultrasonic atomization, magnetized water dust suppression, double
curtains of wind and fog, biological nano-film, and emerging microbial dust
suppressants in the field of dust. The actual application compares and analyzes the advantages and disadvantages of different
dust removal technologies. The current three directions of mine dust
prevention and control are pointed out: the prevention and control of
respirable dust, hydrophobic dust, and secondary dust, and the prospects for
future development trends. Given the treatment of respirable dust, it is
necessary to strengthen the research on the
dust generation mechanism under different working conditions and to
explore the migration and settlement laws of respirable dust by constructing a
numerical model of dust dynamics; for the treatment of hydrophobic dust,
further research on the microphysical and chemical properties of coal dust is
needed. The relationship between wettability
and continuously optimizing the wetting agent; for the prevention and
control of secondary dust in coal mines, emerging microbial dust suppression
technologies need to be developed to explore the micro-action between
microorganisms and coal dust molecules to achieve green prevention and control
of dust.
