【Abstract】 In order to improve the application of ESP in coal industry, some measurcs to prevent ignition or explosion have been reported when ESP is used to collect coal dust and the ignition test is conducted, repeatedly, on coal powder fetched from worksite with far greater energy for discharging sparks in easy ignition conditions. The experimental results prove that there is no probability of ignition or explosion when ESP is used to collect coal dust in coal transport更多还原
