Abstract

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

Изобретение относится к горному делу и может быть использовано для разработки алмазоносных трубок, залегающих в сложных горно-геологических условиях. Способ разработки месторождения полезных ископаемых включает вскрытие месторождения скважинами и подземными горными выработками - шахтными стволами и квершлагами, разрушение полезного ископаемого через скважины, выдачу разрушенного полезного ископаемого через подземные горные выработки. Разработку алмазоносной трубки ведут панелями в форме кольцевых цилиндров. Панель по ширине формируют добычными блоками, состоящими из трех радиально расположенных выемочных камер в форме прямых цилиндров, касающихся между собой образующими. Продвижение фронта очистных работ в панели осуществляют путем выемки полезного ископаемого в смежные с отработанными и заложенными блоками по направлению к капитальному штреку, пересекающему трубку диаметрально на горизонте выпуска. Между отрабатываемыми панелями оставляют временные целики в форме кольцевых цилиндров, которые разрабатывают во вторую очередь панелями, после частичной или полной закладки выработанного пространства смежных с временными целиками панелей. Подготовку панелей к эксплуатации осуществляют кольцевыми штреками, пройденными на горизонте выпуска вдоль оси, делящей ширину каждой панели пополам. Подготовку добычных блоков к очистной выемке производят путем проходки из кольцевых штреков двух камер, расположенных симметрично по отношению к продольной оси штрека. В кровле кольцевых штреков и камер размещают забой пилот-скважины пробуренных в центре выемочных камер. Добычу полезного ископаемого в пределах контуров выемочных камер производят буровыми установками, расположенными на дневной поверхности путем расширения пилот-скважин породоразрушающим инструментам, навешиваемым на буровую колонну в кольцевом штреке и камерах. Разрушенное полезное ископаемое магазинируют в выработанном пространстве выемочных камер. В интервале глубин кратерной части трубки оставляют предохранительный целик и под его основанием формируют несущий целик в форме прямого цилиндра, диаметр которого превышает диаметр трубки, расположенный в плоскости сечения основания целика. Суммарная высота предохранительного и несущего целиков по меньшей мере равна или превышает мощность обводненных вмещающих пород. Несущий целик возводят из кольцевых цилиндров, образованных выемочными камерами, с закладкой выработанного пространства по направлению от границы трубки с вмещающими породами к ее центру с опережением скорости возведения несущего целика скорости продвижения фронта очистных работ в панелях.The invention relates to mining and can be used to develop diamond-bearing pipes lying in difficult mining and geological conditions. A method of developing a mineral deposit includes opening a deposit with boreholes and underground mine workings — mine shafts and crosshairs, destroying the mineral through the wells, and discharging the destroyed mineral through the underground mining. The development of a diamondiferous tube is carried out by panels in the form of annular cylinders. The width of the panel is formed by mining blocks, consisting of three radially located recess chambers in the form of straight cylinders that are tangential to each other. The front of the treatment works in the panel is promoted by extracting minerals into adjacent blocks with spent and laid blocks in the direction of a major drift crossing the pipe diametrically at the discharge horizon. Temporary pillars in the form of annular cylinders are left between the panels to be worked out, which are developed in the second place by the panels, after a partial or full laying of the worked out space of the panels adjacent to the temporary pillars. Preparation of panels for operation is carried out by annular drifts, passed on the production horizon along an axis dividing the width of each panel in half. The preparation of mining blocks for the treatment recess is carried out by sinking from the annular drifts of two chambers located symmetrically with respect to the longitudinal axis of the drift. In the roof of annular drifts and chambers, the face of the pilot well drilled in the center of the extraction chambers is placed. Mining within the boundaries of the extraction chambers is performed by drilling rigs located on the day surface by expanding pilot wells with rock cutting tools hung on the drill string in an annular drift and chambers. Destroyed minerals store in the mined-out space of the extraction chambers. In the depth interval of the crater part of the tube, a safety pillar is left and a bearing pillar is formed under its base in the form of a straight cylinder, the diameter of which exceeds the diameter of the tube located in the sectional plane of the pillar base. The total height of the safety and bearing pillars is at least equal to or greater than the power of the watered enclosing rocks. The bearing pillar is erected from the annular cylinders formed by the extraction chambers, with the laying of the worked-out space in the direction from the boundary of the tube with the host rocks to its center ahead of the speed of raising the bearing pillar of the speed of advancement of the front of the treatment works in the panels.
