Description
- , .. t . -Изобретение относитс к горной промы1ш:енности и может бить использвано при подземной разработке с отбойкой руды скважинами, самотечным выпуском ее. через воронки и дучки и доставкой отбитой руды скреперным установками.- .. t. - The invention relates to the mining industry: can be used and is used in underground mining with ore blasting wells, self-flowing release of it. through funnels and duchki and delivery of broken ore scraper installations.
Известен способ самотечного выпуска руды из дучек с последующей доставкой ее скреперными установками 1 ..There is a method of gravity release of ore from duchek with subsequent delivery of its scraper installations 1 ..
Недостатком этого -способа вл етс относительно низка производительность скреперной доставки из-за возникающих в дучках зависаний и трудность регулировани объемов выпуска руды по лучкам, что приводит к повышению потерь, и разубоживани РУДЫ.The disadvantage of this α-method is the relatively low productivity of scraper delivery due to hangs occurring in the duchki and the difficulty of controlling the ore output volumes across the beams, which leads to increased losses, and dilution of the ORE.
Известен также способ самотечного вьшуск.а руды из дучек, включающий проведение выпускных и скреперной выработок и доставку руды 2 .There is also known a method of gravity discharge. Ore from duchek, which includes carrying out final and scraper excavations and delivery of ore 2.
Недостатком дйнного способа вл етс сравнительно низка устойчивость выработок днища, невозможность регулировани процесса выпуска руды.The disadvantage of this method is the relatively low stability of the workings of the bottom, the impossibility of regulating the process of ore production.
Цель изобретени - повышение устойчивости выработок днища и обеспечение регулировани процесса выпуска ,The purpose of the invention is to improve the sustainability of the workings of the bottom and ensure the regulation of the production process,
Поставленна цель достигаетс тем, что почву скреперной выработки углубл ют напротив выпускных дучек, причем высоту скреперной выработки принимают равной-.The goal is achieved by the fact that the soil of the scraper excavation is deepened opposite the discharge ducts, and the height of the scraper excavation is assumed to be equal to -.
