FIELD: method for exploiting diamond pipe. SUBSTANCE: method for exploiting minerals deposits includes opening the deposit with wells and underground mining through mine shafts and crosscuts, destroying rock through the wells, delivering destroyed minerals through underground mine working. Exploitation of diamond-bearing pipe is carried out with panels in the form of ring cylinders. Panel comprises blocks installed along panel width. The block includes three digging breasts in the form of straight cylinders with their generatrices coming in contact with each other. Front of cleaning motion in a panel is carried out by digging minerals to adjoining blocks. Temporary solids are retained between spent panels. The solids are in the form of ring cylinders dug in the second order after partial or complete backfilling of worked off space of panels adjoining temporary solids. Preparation of panels to operation is carried out by ring connectors run on release horizon along axis dividing width of the panel by two. Preparation of digging blocks to clean digging is carried out by working from ring connectors of two breasts placed symmetrically about lengthwise axis of the connector. Pilot-well bottom is placed in roof of ring connectors and breasts. Minerals exploitation within margin of digging breasts is carried out by widening pilot-wells by rock destroying tool hung from drill casing in ring connector and breasts. Destroyed minerals are stacked in worked off space of digging breasts. Safety solid is retained, and bearing solid is formed under the base of the latter in the form of a cylinder. Diameter of the bearing solid exceeds diameter of pipe placed in the plane of solid base cross section. Summary height of the safety and bearing solids is at least equal to or exceeds thickness of flooded hoist rocks. Bearing solid is erected of ring cylinders formed by digging breasts with backfilling worked off space along direction from pipe boundary with hoist rocks towards its center. EFFECT: high efficiency. 4 cl, 7 dwg |
