Description
Изобретение относитс к горной промышленности и может использовать с при вскрытии месторождений полез ных ископаемых при открытой разработке . . . Известен способ вскрыти месторождений полезных ископаемых при от крытой разработке, включающий прЬведение горизонтальных выработок крудоспусков 1). Известен также способ вскрыти .месторождений полезных ископаемых при открытой разработке, включающий проведение стволов, горизонтальных выработок от. них и рудоспус.ков,соеДин югдах горизонтальные выработки с горизонтами карьера 2, Однако такие способы характеризу ютс значительным объемом .капитального строительства и недостаточной эффективностью разработки. Цель изобретени - повьушение эффективности разработки и снижение капитальных затрат. Это достигаетс тем, что вскрыти провод т вертикальным основным и вспомогательныют стволами на глубину выше дна кар.ьера с размещением устьев стволов в вер-хней отработанн части карьера, причем горную массу транспортируют по основному стволу в верхнюю часть карьера с одновременным проветриванием последне.го через дополнительный ствол; по мере понижени горных работ углубл ют дополнительный ствол и после проведени от него горизонтальной выработки последнюю снизу вверх соедин ют сосновным стволом; от дополнительного ствола к рудоспускам провод т горизонтальную выработку параллельно выработке , проводимой от основного ствола, а горизонтальные выработки провод т к стволам из рабочей зоны карьера. . На чертеже приведен а схема вскрыти карьерного пол . Способ заключаетс в следующем, Месторождение в проектных контурах 1 отрабатывают карьером с временными бортами 2. После формировани участка посто нного борта 3 на глубину 120-160 м вскрытие осуществл ют основным стволом 4 и дополнительным 5 на глубину выше дна карьера 6 с оставлением устьев вертикальных стволов в верхней отработанной части карьера. От стволов 4 и 5 в направлеThe invention relates to the mining industry and can be used when opening mineral deposits in open pit mining. . . There is a known method for exposing mineral deposits in opencast mining, including the use of horizontal workings of crudes 1). There is also known a way to open up mineral deposits in open pit mining, including carrying out shafts, horizontal workings from. them and orespusk.kov, soydin yugdah horizontal workings with the horizons of the open pit 2, However, such methods are characterized by a significant amount of capital construction and lack of efficiency of development. The purpose of the invention is to increase the efficiency of development and reduce capital costs. This is achieved by opening up the main vertical and auxiliary trunks to a depth above the bottom of the quarry with placement of the mouths of the trunks in the top of the spent part of the quarry, the mountain mass being transported along the main trunk to the upper part of the quarry with simultaneous ventilation of the latter through additional trunk; as the mining works decrease, the additional trunk is deepened and, after horizontal generation from it, the latter is joined from the bottom up by a pine trunk; from the additional trunk to the ore passes, horizontal development is carried out parallel to the excavation conducted from the main trunk, and horizontal development is conducted to the trunk from the working area of the open-pit. . The drawing shows a diagram of the career floor. The method is as follows. The field in project circuits 1 is mined with a quarry with temporary sides 2. After forming a section of the permanent bead 3 to a depth of 120-160 m, the main trunk 4 and an additional 5 to the depth of the bottom of the quarry 6 are opened, leaving the mouths of vertical trunks in the upper part of the quarry. From trunks 4 and 5 in direction
