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

Science in China Series A: Mathematics, 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 ...
