Abstract
1. Способ разработки рудных залежей системой этажного обрушения с активным гибким разделяющим перекрытием, включающий проходку подготовительных и нарезных выработок, монтаж гибкого перекрытия в висячем боку рудного тела, отбойку и торцевой выпуск под ним отбитой руды из блока через подэтажные выработки, отличающийся тем, что по углам блока проходят выработки по мощности рудного тела вкрест его простирания, после чего бурят из них веерные комплекты скважин в висячем боку рудного тела параллельно плоскости залегания рудного тела для проходки отрезной щели, после отбойки которой производят выпуск отбитой руды через подэтажные выработки, затем во всех выработках, пройденных по углам, монтируют лебедки с тросами, после чего тросы с верхнего горизонта спускают до уровня нижней отметки блока, присоединяют к ним активное гибкое перекрытие, выполненное из нескольких рядов эластичных замкнутых оболочек, соединенных и воздуховодом для подачи сжатого воздуха с компрессором, протягивают перекрытие по мере монтажа в отрезную щель до верхнего горизонта, заполняют оболочки воздухом до рабочего давления, натягивают гибкое перекрытие тросами, после чего производят операции очистной выемки, причем по мере отработки запасов блока тросы периодически подтягивают, после отработки запасов блока воздух из оболочек спускают с помощью воздуховода для сброса воздуха, и вытягивают перекрытие на верхний или нижний горизонт. ! 2. Способ по п.1, отличающийся тем, что ширину каждого ряда оболочек принимают равной половине ширины подэтажа, причем каждый ряд оболочек имеет свой воздуховод для подачи и сброса давления сжатого воздуха 1. The method of developing ore deposits by a system of floor caving with an active flexible dividing overlap, including the excavation of preparatory and rifted workings, installation of a flexible overlap in the hanging side of the ore body, breaking and end release under it of beaten ore from the block through the floor workings, characterized in that the corners of the block are driven by the ore body thickness across its strike, after which they are drilled out of fan sets of wells in the hanging side of the ore body parallel to the ore body bedding plane for passing Odds of the cutting gap, after breaking which produce the output of the broken ore through the sub-floor workings, then in all the workings passed through the corners, winches with cables are mounted, after which the cables are lowered from the upper horizon to the level of the lower elevation of the block, they are joined by an active flexible overlap made of several rows of elastic closed shells connected by an air duct for supplying compressed air with a compressor, stretch the ceiling as it is mounted in a cutting slot to the upper horizon, fill the air shells to the operating pressure, pull flexible overlap cables, whereupon operation purification recesses, wherein at least development of reserves cables block periodically tighten, after working air block reserves of the shells are lowered via the duct for the discharge of air, and drawn overlap on the top or bottom horizon. ! 2. The method according to claim 1, characterized in that the width of each row of shells is taken equal to half the width of the sub-floor, and each row of shells has its own duct for supplying and relieving pressure of compressed air
