Preventing dust explosions in coal mines: Methods and current trends

A growing trend of underground coal mining draws close attention to issues of occupational safety. One of the critical factors to govern the rate of mining operations is emission of explosive gases and dust in the limited spaces of roadways per unit time or per ton of rock. In this and in the last centuries, explosions of gas and dust, repeatedly recorded in coal mines in France, US, Poland, South Africa, Japan, China, Ukraine and Russia, jointly caused tens of thousands of deaths. This article gives the statistics of the largest accidents connected with explosions of hybrid dust/methane/air mixtures in coal mines worldwide, and characterizes the main causes of these tragedies, including imperfection of antidust activities, departure from the dust suppression procedure, sequence and periodicity, as well as the lack of the appropriate production control. The scope of the discussion embraces the present-day methods and approaches to prevention and localization of coal dust explosions, and their weak points. Some engineering solutions proposed may be of practical relevance, given their proper validation, and can improve dust conditions and reduce probability of dust explosions in coal mines.

Keywords: dust explosion protection in mines, coal dust, gas and dust explosions, dust laying rate, settling coal dust with slate, dust explosion hydroprotection, hydrogel, quality control in dust laying and in settling coal dust with slate.
