The invention discloses an experiment device for testing the coal spontaneous combustion characteristics under rock burst simulated environment. The experiment device comprises a gas chromatograph, a coal container, whose upper part is provided with an opening; an impact force applying mechanism, which is used to apply an impact force on the coal in the coal container; a gas collecting device, which is used to collect the gas in the coal container; and a temperature sensor, which is used to measure the temperature of a coal sample in the coal container. A gas sampling hole is opened in the coal container, and is connected to the gas inlet of the gas chromatograph through the gas collecting device. The provided experiment device can effectively simulate the rock burst environment, then further obtains the coal spontaneous combustion characteristics under the rock burst environment, thus can effectively guide the prevention of fire in a coal mine, and improves the coal spontaneous combustion prediction and alarming system.
Description
technical field [0001] The invention belongs to the technical field of testing coal spontaneous combustion characteristics, and in particular relates to an experimental device for testing coal spontaneous combustion characteristics in a rock burst simulation environment. Background technique [0002] 56% of coal mines in the country are at risk of spontaneous combustion, causing direct and indirect economic losses of nearly 10 billion yuan each year. The spontaneous combustion of coal is affected by many factors. Different scholars have studied it from the aspects of moisture, oxygen concentration, and coal particle size, and achieved different results. However, few scholars have studied the impact of mine pressure and rock burst on coal spontaneous combustion, and have linked mine pressure with coal spontaneous combustion, resulting in a lack of research in this area. As the security requirements are getting higher and higher, the research on this aspect is more and more u...
