Analysis of explosion pressure and residual gas characteristics of micro-nano coal dust in confined space

Journal of Loss Prevention in the Process Industries, 2020
Abstracts In order to study the explosion characteristics of micro and nano-sized coal dust, a 20L spherical explosion test device was used to compare and analyze the explosion pressure characteristics and residual gas characteristics of five kinds of micro-nano particle dusts of 800 nm, 1200 nm, 45 μm, 60 μm and 75 μm under five concentrations (100 ...

Mechanism research of gas and coal dust explosion

Journal of Coal Science and Engineering (China), 2009
Combined with the experimental results from the large tunnel of the Chongqing Research Institute, the mechanism of gas and coal dust explosion was studied. Some concepts about gas and coal dust explosion were introduced such as the form condition and influential factors.

Experiment study on the propagation laws of gas and coal dust explosion in coal mine

Journal of Coal Science and Engineering (China), 2009
The experiment of gas and coal dust explosion propagation in a single laneway was carried out in a large experimental roadway that is nearly the same with actual environment and geometry conditions. In the experiment, the time when the gas and coal dust explosion flame reaches test points has a logarithmic function relation with the test point ...

Coal Dust and Gas Explosion Suppression by Barriers

1987
Explosion suppression barriers are devices that contain fire extinguishants that are activated to disperse at some critical point during the propagation of an explosion to suppress it. Suppression of coal dust explosions using barriers (both triggered and passive) has been investigated by the U.S. Bureau of Mines. The work reported in the present study

Study on the inhibition influence on gas explosions by metal foam based on its density and coal dust

Journal of Loss Prevention in the Process Industries, 2018
Abstract Metal foam is another type of material that can inhibit gas explosion flames and pressure waves. However, there are continuous explosions and coal dust explosions in the coal mine; thus, research on metal foam's inhibition performance under the environment of coal dust and its destructive characteristics after the explosion are necessary.
