METHOD OF DEVELOPMENT OF INCLINED ORE DEPOSITS IN RANGE OF BEDDING ANGLES 15-35 DEGREES AND THICKNESS OF ORE BODIES 15-30 METERS WITH CAVING OF ORE AND SURROUNDING ROCKS Russian patent published in 2015 - IPC E21C41/22 

FIELD: mining.

SUBSTANCE: method includes execution of preparatory drivings, ore room-driving to the full thickness of ore body with leaving of ore pillars, a induced caving of the leaning rocks into room space, an breaking of pillar and extraction of ore from pillars under caved rocks. The rooms and pillars are arranged along the course of ore body, and developments through which the access to drilling and drilling-and-delivery drives is made, are placed in interblock pillars. Drilling rooms from which the caving of rocks into rooms is performed, are performed in the leaning rocks above rooms, and the volume of the beaten-off rocks provides filling of the excavated space at least to the height of rooms with subsequent self-caving of leaning rocks. breaking of ore pillars is performed layer-by-layer together with the leaning rocks, and sublevel caving of the ore beaten off from pillar is conducted under the caved rocks. Rock from cut developments is loaded into excavated rooms. Ore from rooms is loaded by high-performance self-propelled equipment, both with manual, and with remote control.

EFFECT: high-performance ore production from inclined ore deposits in the range of bedding angles 15-35 degrees and the thickness of ore bodies 15-30 meters by optimisation of parameters of ore losses, impoverishment, volumes of preparatory drivings.
