【Abstract】 An airtight tube with thin wall for testing deflagration of coal mine explosives was set up based on the analyses of up-to-date methods of deflagration testing. The deflagration trend of some powder explosive compositions was tested according to the new standard of coal industry. The determination of pressure-time history in the closed tube is the first attempt for evaluation of deflagration trend of coal mine explosives.更多还原
