Reasonable controlling of the coal powder production has become a key factor in CBM well’s high and steady yield. However, the forming mechanism and type of coal powder is not systematically studied so far due to the weak of theoretical basis and the lack of information on engineering practice in past. Based on the domestic and foreign literatures, starting from the coal petrography features, by using microcosmic & ultra-microscopic method and combining with engineering practice, the main recognitions are concluded as follow: (1) Through the mechanical model of coal instability failure under the engineering disturbance, the coal transformation is influenced by many factors such as structure, formation, component, coalification degree and gas generation and (and liquid) release. (2) By combining the rock mechanical properties and the on-site CBM wells production, the reason of coal powder production is generally analyzed, the types of coal powder output is classified and its output mechanism is discussed. It is of great practical significance and theoretical reference for the CBM development.Keywords
