METHOD OF THE LOW AND MEDIUM POWERED ORE BODIES PREPARATION, CUTTING AND MINING Russian patent published in 2017 - IPC E21C41/22 

FIELD: mining engineering.

SUBSTANCE: method of the low and medium powered ore bodies preparation, cutting and mining comprises the producing block reserves development by means of a system "Horizontal slices with the consolidating stowing" with the downward working when the 3-slices stocks from one slicing cross cut are mined-out. The producing block is mined-out in parts of 3 layers at a layer height of 3 m, in a base layer - 0.0 m there is a layerwise cross cut. The crossing track to the sublayer is went through on completing of a work on a layer mining. The divided cross cut in the sublayer is went through. The layer mining is carried out from this cross cut. The ore transportation is carried out through the crossing track till the base layer millhole. All the actions are repeated for the third layer after the layer mining. The cleaning stopes are discharged by the consolidating stowing at all layers after the actual mining. The layerwise cross cuts are not discharged by the consolidating stowing.

EFFECT: invention allows to keep costs on the ore crop down, to enhance the blocks stocks mining tempo, to cut down the scopes of first mining and stowing operations.
