Abstract

To study the initial speed of methane emission computation is very important. It means that the coal which contains gas is completely exposed to the air. The gas from the adsorption state transforms into the free state. The index reflects that the speed of the coal seam gas spread is concerned with the gas of the coal content, pore structure, and surface properties of the pore. State regulations provide that the initial speed of methane emission is an important index for coal seam outburst identification and forecast. However, the test method of the initial speed of methane emission is not perfect. The result is varied because the laboratory and the operating personnel are different. In addition to the above factors, it is concerned with the temperature and radiation pressure. This paper mainly studies the relationship of the initial speed of methane emission with the temperature and radiation pressure and investigates the previous research and experimental methods to determine whether they can be improved with a mathematical formula.
