[0002] Gas coal sample is a coal sample specially collected to determine the gas composition and content in coal seams. It is taken in a borehole or tunnel with a closed sampler to determine the gas composition (carbon dioxide, nitrogen, methane, etc.) and the gas content per gram of combustibles. It is an important data for evaluating the gas content and gas grade of coal mines, and is also an important reference for coal mine well construction design. When testing the gas content in coal samples, take a certain amount of coal blocks, break them into particles, and then use a crusher for closed crushing and testing until the instantaneous flow rate is less than 2, and then wait for 3 minutes before stopping.
