Abstract

FIELD: mining. SUBSTANCE: method for exploitation of steeply dipping underground formations includes opening the formation by a system of such underground mine workings as mine shafts, crosscuts and vertical wells run from original ground; forming six digging wells of vertical wells with remaining interbreast solids, subsequent digging interbreast solids, delivering destroyed minerals to the surface through underground mine workings. Exploitation of diamond bearing pipe is carried out by parallel panels comprising digging blocks. Digging minerals from digging block is carried out working four main riser breasts from vertical wells. Digging breasts are inscribed in parallelepiped of square cross section in plane. Vertical and horizontal faces of which are the faces of digging block along height and width of the panel. Star-like solid is retained in the center of digging block, as well as solids adjoining vertical boundaries of the block in the form of prisms, form of spherical faces of which corresponds to the form of lateral cylindrical surface of digging breast with central angle equal to 90 . Loss of minerals in solids within boundaries of digging block does not depend on diameter (D) of main digging breasts and accounts for 21 % of balance storage of digging block. Loss of minerals in solids placed within boundaries of digging block is diminished by working in the center of star-like solid of the digging block in progress and in the centers of solids from vertical wells (is not indicated on drawings) of additional riser breasts with diameters (d) specified under formula d = 0.414D. Loss of minerals in retained solids within boundaries of digging block does not depend on D of main digging breasts and d of additional digging breasts and accounts for 8 per cent of balance storage of digging block of one suppressed. EFFECT: high efficiency. 2 cl, 8 dwg

Изобретение относится к горному делу и может быть использовано преимущественно для разработки алмазоносных трубок, угольных месторождений, залегающих в сложных горно-геологических условиях. Способ разработки крутопадающих подземных формаций включает вскрытие формации системой подземных горных выработок - шахтными стволами, квершлагами и вертикальными скважинами, пройденными с дневной поверхности, формирование из вертикальных скважин выемочных камер с оставлением междукамерных целиков , последующую выемку междукамерных целиков, выдачу разрушенного полезного ископаемого на поверхность через подземные горные выработки Разработку алмазоносной трубки ведут параллельными панелями, состоящими из добычных блоков. Выемку полезного ископаемого из добычного блока осуществляют путем проходки из вертикальных скважин четырех основных восстающих выемочных камер, вписанных в параллелепипед квадратного сечения в плане, вертикальные и горизонтальные грани которого являются границами добычного блока по высоте и ширине панели. В центре добычного блока оставляют звездообразный целик, а также целики, примыкающие к вертикальным границам блока, в виде призм, сферические грани которых соответствуют по форме боковой цилиндрической поверхности выемочной камеры с центральным углом, равным 90oС. Потери полезного ископаемого в целиках в пределах границ добычного блока не зависят от диаметров основных выемочных камер и составляют 21% от погашенных при добыче балансовых запасов добычного блока. Снижение потерь полезного ископаемого в целиках, расположенных в пределах границ добычного блока, осуществляют путем проходки в центре звездообразного целика отрабатываемого добычного блока и в центрах целиков, примыкающих к вертикальным границам, смежных с отрабатываемым добычных блоков, из вертикальных скважин дополнительных восстающих выемочных камер, диаметры d которых определяют по формуле d=O,414D. Потери полезного ископаемого в оставшихся целиках в пределах границ добычного блока не зависят от диаметров основных и дополнительных выемочных камер и составляют 8% от погашенных при добыче балансовых запасов добычного блока.The invention relates to mining and can be used mainly for the development of diamond-bearing pipes, coal deposits, occurring in difficult geological conditions. A method for developing steeply dipping underground formations involves opening a formation with a system of underground mine workings — mine shafts, crosshairs and vertical wells traversed from the day surface, forming excavation chambers from vertical wells with interchamber pillars remaining, subsequent excavation of interchamber pillars, and issuing destroyed minerals to the surface through underground mining workings. The development of a diamondiferous pipe is carried out by parallel panels consisting of mining blocks. The extraction of minerals from the mining block is carried out by sinking from vertical wells of four main uprising mining chambers inscribed in a box of square cross section in plan, the vertical and horizontal faces of which are the boundaries of the mining block in height and width of the panel. A star-shaped pillar is left in the center of the mining block, as well as pillars adjacent to the vertical boundaries of the block, in the form of prisms, the spherical faces of which correspond in shape to the lateral cylindrical surface of the extraction chamber with a central angle of 90 ° C. Mineral losses in pillars within the boundaries the mining block does not depend on the diameters of the main extraction chambers and make up 21% of the balance reserves of the mining block paid off during mining. Reducing mineral losses in pillars located within the boundaries of the mining block is carried out by sinking in the center of the star-shaped pillar of the worked out mining block and in the centers of pillars adjacent to the vertical boundaries adjacent to the worked out mining blocks from the vertical wells of additional rising excavation chambers, diameters d which are determined by the formula d = O, 414D. Mineral losses in the remaining pillars within the boundaries of the mining block do not depend on the diameters of the main and additional extraction chambers and make up 8% of the balance reserves of the mining block repaid during mining.
