t Изобретение относитс к горной промышленности и может быть использовано дл добычи полезного ископаемого при разработке мощных рудных залежей.t The invention relates to the mining industry and can be used for mining in the development of powerful ore deposits.

Известен способ разработки мощных рудных месторождений i, -камерно-столбовой системой с послойной выемкой l.There is a method of developing powerful ore deposits i, chamber-pillar system with a layered excavation l.

Недостатком щанного) способа вл етс сложность и дороговизна рабог и относительно Низка производительность труда забойных рабочих.The disadvantage of this method is the complexity and high cost of work and the relatively low productivity of downhole workers.

Известен также способ разработки моганых рудных месторождений с разделением на слои, выемкой их камерно-столбовой системой и принудительным обрушением 2Х There is also known a method of developing mineral ore deposits with the division into layers, excavation them with a chamber-and-pillar system and a forced collapse of 2X

Недостатком указанного способа влдаотс сравнительно большие потери к разубоживание руды.The disadvantage of this method is a relatively large losses to the dilution of the ore.

Целью изобретени вл етс сн1йкение потерь и разубоживани руды. Достигаетс эт тем, что рудное тело обрабатываютв три сло с «угработкой в Первую очередь среднего сло камерно-столбовой системой, последгошей закладкой выработанного пространстаа камеры твердеющей смесью с оставленном верхней часThe aim of the invention is to reduce losses and dilute ore. This is achieved by the fact that the ore body is treated in three layers with "processing, first of all, the middle layer with a chamber-pillar system, followed by the laying of the developed chamber space with a hardening mixture with the upper part left).

ти камеры незаложенной, затем отрабатывают верхний и нижний слои, причем верхний слой с принудительным. обру1ие1шем, а ниж1шй камерно-сголбовой системой, це«икинижнего сло располага«уг междуде вка /щ среднего опо с последующей выемкой целиков среднего сло и выпуском отбитой руды верхнего сло через образованные отверсти , а также тем, что во вторую очередь отбивают руду верхнего сло , а затем отрабатывают камеру нижнего сло или во вторую очередь отрабатывают камеру нижнего сло , а затем отбивают руду верхнего сло ..These chambers are unencumbered, then the upper and lower layers are worked out, with the upper layer being forced. the lower and lower-level chamber-hollow system, the bottom of the lower layer has a “space between the middle / middle middle” followed by excavation of the middle layer and discharging the broken ore of the upper layer through the holes formed, and also secondarily beat the ore of the upper layer and then they work out the chamber of the lower layer or, in the second place, work out the chamber of the lower layer, and then beat off the ore of the upper layer ..

Claims

; The mine deposit is divided into layers and, first of all, the middle layer is removed by the chamber-and-pillar development system, leaving the pillars 1 followed by a bookmark, the worked up space by the hardening mixture 2 and leaving the upper part of the chamber unencumbered. Then the ore of the upper layer 3 is collapsed on the surface of the artificial massif, after which the lower layer 4 is worked out with a chamber-and-pillar system of development with simultaneous release of the collapsed ore of the upper layer through holes 5 formed in the artificial massif as a result of mining the pillars of the middle layer. The application of the proposed method of development allows the use of high-performance self-propelled drilling, loading and delivery, and other o6opyMOBaiaie: Claim 1. The method of developing powerful ore deposits with separation into layers, their chamber-and-pillar system and compulsory collapse. , in order to reduce losses and dilution of ore, the ore body is processed into three layers, with the first working out of the middle layer by the chamber-and-pillar system, followed by laying out the developed space The hardening mixes with ocTasnenHeNf top) of the first part of the chamber are unencumbered, then the upper and lower layers are worked out, the upper layer with a forced collapse, and the lower layer is chamber-pillar system, the lower layer of the lower layer is positioned between the pillars of the middle layer and the subsequent excavation of the middle layer the release of the broken ore of the upper layer through the holes formed. 2. The method according to p. 1, about a hl and h y and that with the second turn beat off the ore of the upper layer, and then work the chamber of the lower layer. 3. The method according to paragraphs. 1 and 2, that is, with the fact that the chamber of the lower layer is worked out secondarily, and then the ore of the upper layer is beaten off.
