Description
Известны способы поддержани кровли в очистном пространстве при разработке, например, рудных месторождений путем оставленпч рудных целиков или возведени штангового креплени .Methods are known for maintaining the roof in the clearing space when developing, for example, ore deposits, by leaving the ore pillars or building a sucker rod.
Оставление целиков в очистном пространстве приводит к значительным потер м руды, а последующа отработка этих целиков малопроизводительна , св зана с большим разубоживанием полезного ископаемого.Leaving the pillars in the clearing space leads to significant loss of ore, and the subsequent mining of these pillars is inefficient, associated with a large dilution of the mineral.
Применение штанговой крепи не всегда дает по„ ожительные резульf aTbi и не обеопечива т должную безопасность работ.The use of post support does not always give positive results and does not ensure proper safety of work.
Предлагаетс способ создани устойчивой кровли или других обнажений горных пород .путем применени струнобетона, который нашел широкое применение в строительном деле.A method is proposed for creating a stable roof or other outcrops of rocks by applying string concrete, which has found wide application in construction.
Параллельно плоскости обнажени или в ином направлении бур чглубокие скважины, в которые закладываютс пучки струн, которые нат гивают , а затем скважины заполн ют бетоном. При этом считают, что горные породы ведут себ при армировании так же, как и бетонные сооруж ни .Parallel to the plane of the outcrop or in the other direction, drilled deep wells, in which string beams are laid, which pull, and then the wells are filled with concrete. At the same time, it is believed that the rocks behave during reinforcement in the same way as concrete structures or.
Применение дл армировани высокопрочной проволоки (сг 18000 кг/см }, предварительно напр женной до 12000 кг/см, обеспечит передачу бетону высоких предварительных напр жений сжати , которые он должен в свою очередь передать горны.м породам. Это обеспечит устойчивость горных пород на участ ках, обуренных скважинами и армированных напр женным струнобетоном.The application for reinforcing high-strength wire (cr 18000 kg / cm}, prestressed to 12000 kg / cm, will ensure the transfer of high compressive prestress to concrete, which it must in turn pass the mountain to rocks. kakh, drilled with wells and reinforced with strained string concrete.
Предмет изобретени Subject invention
Способ укреплени поверхности обналсений горных пород, отличающийс тем, что, с целью придани устойчивости иородам, параллельно ПЛОСКОСТИ обнажени или в ином направлении бур т скважины, которые заполн ют струнобетоном с предварительно напр женной арматуройA method of strengthening the surface of rock deposits, characterized in that, in order to impart stability to the rocks, parallel to the PLANE of exposing or in another direction, wells are drilled, which are filled with pre-stressed reinforced concrete.
