Research on the Suppression of Coal Dust Explosions by Water Barriers

Book Description
Chongqing Coal Research Institute has been conducting experimental research on water barriers to determine their feasibility for installation in underground coal mines in China. The performance tests of 40- and 80-L tubs indicate that when the dynamic wind pressure is equal to or more than 0.16 kg/cm2 they rupture and water disperses to form a spray cloud, which lasts for 75 to 150 ms. The cloud is 7 m long and spreads about 4 m wide. For extinguishing coal dust explosions, water barrier tests were conducted in our experimental gallery (896-m total length and 7.2-m2 cross section). The test results have shown that barriers can effectively suppress coal dust explosions propagating at speeds of 80 to over 700 m/s. It was found that a delay time of from 2 to 1100 ms between barrier operation and flame arrival does not reduce their effectiveness. However, when the flame propagates slowly and the explosion pressure does not develop sufficiently, the barrier can be ineffective. Further research is necessary to improve the tub materials, their design, and their configuration.
