SUBSTANCE: method of development of thick flat-lying coal bed on clots of irregular shape is intended for extraction of coal from sections with limited resources which for economic reasons can not be extracted by means of complex mechanisation. The method includes preparing an extraction pillar by making transport and ventilation entries at a bed roof and a hydro-transport entry at a bed floor with the axis of the hydro-transport entry set-off against the axis of the transport entry to the direction of massif. The extraction pillar is divided into strips with stopes; simultaneously there is assembled a roof bolting while leaving between-stopes massifs virgin. The stopes are made at the bed roof from the transport to ventilation entry. Neighbour stopes are linked with connections. A borehole is drilled approximately along the axis of the stope from the hydro-transport entry to each stope. A hydro-transport slit is cut with a hydro-monitored jet from the head of the borehole to the ventilation entry along the axis of the stope till the bed floor, and in the reverse direction coal is extracted with a hydro-monitor below the stope floor and partially under the massif from the flank side. Transporting of loose coal in mine workings above the stope floor is performed with traditional means, for example with self-propelled car and conveyer, while below the stope floor it is transported in form of pulp. After extraction of coal in stopes there is performed extraction of massif under the transport entry and further - under the ventilation entry by the similar method.
