description	The invention discloses a coal mining device based on cooperative safe and efficient mining of coal and coal bed gas. The coal mining device can realize automatic mining of coal; size classification of coal briquettes is realized while mining is conducted in a coal cutting manner, and intermittent conveying of the classified coal briquettes is performed, so that classified conveying of the coal briquettes with different sizes is facilitated, conveying equipment does not need to be added, the equipment utilization rate is increased, and the coal mining efficiency is improved; according to a cutting coal mining mechanism, an angle support assembly is arranged to enable a cutting knife to vibrate slightly in the cutting depth direction during cutting, the coal mining efficiency can be effectively improved, meanwhile, the problems of knife clamping, so that the problems of knife jamming, knife clamping and the like are prevented while the mining efficiency is effectively improved; coal dust can be conveniently di
