Coal-Dust and Explosions [PDF]
THOSE who have given the labours and conclusions of workers antecedent to, and contemporaneous with, Mr. W. Galloway, on the subject of the part played by coal-dust in mine explosions, the careful consideration which these merit in common with the results and writings of that zealous exponent of the question, will hardly feel disposed to concur in his ...

Study on effect of oxygen volume fraction on explosion characteristics of silo mixed coal
To study the effect of oxygen volume fraction on the explosion characteristics of silo coal, an experiment was conducted on the explosion parameters(maximum pressure pmax, maximum pressure rise rate (dp/dt)max , and explosion index Kst ) of mixed coal in

Comprehensive research method for explosive coal dust
The article briefly analyses the explosion and fire hazard properties of coal dust of different dispersions. It is emphasised that many experts working in the field of explosion protection and industrial safety pay insufficient attention to changes in the properties of the dust when reducing its dispersity.

Application of protection means against explosions in underground mines [PDF]
Underground coal mines explosions generally arise from the inflammation of a methane/air mixture. This explosion can also generate a subsequent coal dust explosion. Traditionally such explosions have being fought eliminating one or several of the factors

ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
