(54) СПОСОБ РАЗРАБОТКИ КРУТОПАДАКЩИХ МАЛОМОЩНЫХ РУДНЫХ МЕСТОРОЖДЕНИЙ(54) METHOD FOR DEVELOPING SUSPENSIVE LOW-PREPARED ORE DEPOSITS
Изобретение относитс к горной промышленности и может быть исполь-. зовано при подземной разра ботке крутопадаюцих рудных тел малой мо1цности.The invention relates to the mining industry and can be used. It is called for the underground mining of steeply low-grade ore bodies.
Известен способ нисход щей выемки -трудных залежей или междукамерных целиков с применением передовой траншеи или цели, под прикрытием многослойного древесного настила из бревен 1 .There is a method of downward excavation — difficult deposits or interchamber pillars using an advanced trench or target, under the cover of a multi-layered timber floor of logs 1.
Известен также способ разработки крутопадаюы.их рудных тел малой мощности блоками, включаю1чий нисход щую послойную .выемку руды сплошным забоем от восстающих, крепление рама-ми , укладку дерев нного настила непосредственно на почве или на распорках , закладку подрываемыми породами и скреперную доставку отбитой руды к рудоспускным отделени м восстающих .2 .There is also known a method of developing steeply low-grade ore bodies in small capacity, including a descending layer-by-layer ore extraction with a solid face from the rebels, fixing frames, laying wooden decking directly on the soil or on struts, laying laying up rocks and scraper delivery of broken ore ore dischargers and rebels .2.
Недостатки известных способов заключаютс в том, чго при отработке сло руды под настилом, который уложен непосредственно на почве или на распорках, вследствие отсутстви пространства между взрываемым массивом руды и настилом, настил может повредитьс взрывом, что повлечет за собой просыпание закладочного,The disadvantages of the known methods are that when mining the ore beneath the flooring, which is laid directly on the soil or on the struts, due to the absence of space between the exploding ore mass and the flooring, the flooring may be damaged by an explosion, which will cause spilling of the backfill,
материала на отбитую руду и ухудшение безопасных условий труда в очистном забое.material for broken ore and deterioration of safe working conditions in the downhole.
Целью изобретени вл етс повы1йё-. ние безопасности работ и сокращение расхода крепежных материалов.The aim of the invention is to improve. improvement of work safety and reduction in the consumption of fixing materials.
Поставленна цель достигаетс тем, что настил устанавливают над очистным пространством выемочного сло The goal is achieved by installing the flooring above the cleaning space of the excavation layer.
10 и по мере выемки слоев -опускают его путем перестановки распорных рудостоек , начина от границ блока и мен направление работВ смежных сло х.10 and as the layers are excavated, they are released by rearranging the spacer mines, starting from the boundaries of the block and changing the direction of work in the adjacent layers.

На чертеже показано отрабатываемое рудное тело по простиранию, вертикальный разрез.The drawing shows the ore body being worked along the strike, a vertical section.
Блок к отработке подготавливают штреками 1 и восстающими 2.The unit for training is prepared with drifts 1 and rebels 2.

Очистную выемку начинают сплошным забоем сверху вниз отбойкой первых нескольких слоев руды от почвы верхнего откаточного штрека 1. Отбитую руду скреперуют к рудоспускным The clearing dredging is started with a solid bottom-to-bottom crushing of the first several layers of ore from the soil of the upper haulage road 1. The broken ore is scraped to the ore-discharge
25 отделени м восстающих 2.25 branches of the insurgents 2.
Дл ограждени очистного пространства 3 в блоке устанавливают р д раздвижных металлических рудостоек 4 от одной границы блока до другой To enclose the clearing space 3, a row of sliding metal mines 4 is installed in the block from one block boundary to another.
