Description
(54) СПОСОБ ВЫЕА1КИ ЦЕЛИКОВ(54) METHOD OF VYE1KI OF PERSONS
Изобретение относитс к горной промышленности и может быть использовано дл выемки целиков при камерно-столбовой системе разработки мощных пологопадающих залежей.The invention relates to the mining industry and can be used for excavation of pillars in a chamber-and-pillar system for the development of powerful gently dipping deposits.
Известен способ выемки ленточных целиков при камерно-столбовой системе разработки полезных ископаемых, при котором после полной отработки камер в блоках и их закладки , отработка междублоковых целиков производитс системой с обрушением руды и ее выпуском через торец или днище.There is a known method of excavating tape pillars in a chamber-and-pillar system for the development of mineral resources, in which, after the chambers in the blocks have been completely worked out and laid, the interblock pillars are worked out with a system of ore collapse and its release through the end or bottom.
Кроме того, известен также способ выемки целиков при камерно-столбовой системе разработки полезных ископаемых с обрушением кровли в выработанное пространство камер и погашением рудных целиков.In addition, there is also known a method of excavation of the pillars in the chamber-and-pillar system of the development of minerals with the collapse of the roof into the worked-out chamber space and the redemption of ore pillars.
Однако эти способы выемки целиков характезируютс сравнительно большими потер ми и разубоживанием руды.However, these methods of excavation of the pillars are characterized by relatively large losses and dilution of ore.
Дл сокращени потерь и разубоживани руды породы кровли над целиками предварительно обрушивают в сторону отработанных камер, затем вынимают под «плавающей потолочной рудный целик.To reduce losses and dilute the rock ore, roofs above the pillars are first crushed towards the spent chambers, then removed under the floating ceiling ore rear sight.
На чертеже показан разрез рудного тела по отрабатываемым камерам.The drawing shows a section of the ore body on the working chambers.

Блок отрабатываетс камерпо-столбопой системой разработки с вв емкой камер 1. Затем в кровле камер глубокими скважинами 2 обрушают породили массив 3 в расчете на большую кусковатость обрушаемых пород и дополнительно образуют разрыхленную зону или пустоту Ч дл разгрузки междублокового целика 5, который затем вынимаетс системами с обрушением.The block is worked out by a camera-and-stolbing development system with advanced chambers 1. Then, in the roof of the chambers, deep boreholes 2 collapsed gave rise to massif 3 based on the large lumpiness of the crushed rocks and additionally form a loosened zone or void H to unload the interblock rear pillar 5, which is then removed from collapse.
В кровле междукамерного целика оставл ют предохранительную потолочину 6, котора по мере выпуска руды опускаетс , предохран вынимаемую руду от разубоживани .A safety ceiling 6 is left in the roof of the interdigit chamber, which lowers as the ore is released, protecting the ore from being diluted.
