BLOCK WORKING METHOD Russian patent published in 1998 - IPC

Abstract RU 2103509 C1

FIELD: mining industry. SUBSTANCE: this relates to underground development of deposits. According to method, underground headings are driven, then created are block bottom, compensation chambers and slots, horizon of undercutting and drilling horizon drifts. Descending bore-holes are drilled for formation of concentrated charges. Made from drilling horizon in block mass by way of drilling conjugated bore-holes are cylindrical, flat and conjugated with them spaces for accommodation of concentrated charges of explosives. Drilling heading is driven at level of drilling horizon to produce sections of compensation slot which is formed by means of drilling blasting spaces and location of flat charges in them. EFFECT: high efficiency. 6 dwg
