METHOD OF PREPARATION AND MINING CONTIGUOUS FLAT SEAMS Russian patent published in 2014 - IPC E21C41/18 E21F1/00 

FIELD: mining.

SUBSTANCE: method comprises sinking of gate road on two seams, holed by slopes, airing dead ends using ventilation systems of local ventilation and broken ore supply from sinking of gate road on the upper seam through the pre-passing wells to the conveyor line mounted on the lower seam. The gate and the belt roads along the lower seam pass in direct order to the border of the working area and their airing is carried out by general shaft depression on turning point scheme using the most remote inter-gate holing. Then sinking of spiral slope to the upper seam is carried out, and then in reverse order the gate road is passed on the upper seam with its airing through the wells, with the fans mounted on them. After holing of the gate road with air gates of the upper seam, airing is carried out on turning point scheme with the movement of air in the direct order on the workings on the lower seam, and with a backward motion of air in the workings of the upper seam.

EFFECT: invention enables to increase the efficiency of development by reducing the scope of development workings and time for preparation of the working area.
