Abstract
Использование: примен етс в горнодобывающей промышленности при разработке мощных крутых пожароопасных пластов дл снижени затрат на подготовку и повышение надежности предотвращени распространени зоны самонагревани с вышележащего подэтажа. Сущность изобретени : проходку монтажной камеры осуществл ют под углом естественного откоса обрушенных пород отработкой поперечно- наклонного сло по простиранию пласта, упрочнение нижнего борта барьерного целика производ т в границах обнажений монтажной камеры, в которой монтируют секции щитового перекрыти под углом естественного откоса обрушенных пород из штрека у кровли пласта, а разрушение пород кровли осуществл ют до начала выемки угл в этаже, этажи отрабатывают сверху вниз с нисход щей выемкой угл в этаже. 5 ил., ел СUsage: it is used in the mining industry to develop powerful steep fire hazardous formations to reduce the cost of preparation and increase the reliability of preventing the spread of the self-heating zone from the overlying subfloor. The essence of the invention: sinking the installation chamber is carried out at an angle of repose of collapsed rocks by working out a transversely inclined layer along the strike of the formation, hardening the lower side of the barrier pillar is performed within the boundaries of the outcrops of the installation chamber, in which sections of the shield panel are mounted at an angle of repose of the collapsed rocks from the drift near the top of the formation, and the destruction of the roof rocks is carried out before the start of the coal mining in the floor, the floors work from top to bottom with the downward coal mining in the floor. 5 ill., Ate C
Description
Изобретение относитс к горнодобывающей промышленности и может быть использовано при разработке мощных крутых пожароопасных пластов.The invention relates to the mining industry and can be used in the development of powerful steep fire hazardous formations.
Целью изобретени вл етс снижение затрат на подготовку и повышение надежности предотвращени распространени зоны самонагревани с вышележащего этажа .The aim of the invention is to reduce the cost of preparation and increase the reliability of preventing the spread of the self-heating zone from an overlying floor.
На фиг. 1 приведена схема подготовки пласта и выемки монтажной камеры; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - схема монтажа щитового перекрыти , укреплени борта межэтажного барьерного целика и разбуривани пород кровли дл принудительного обрушени ; на фиг. 4 - разрез поIn FIG. 1 shows a diagram of the preparation of the reservoir and the recess of the mounting chamber; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a diagram of mounting a shield panel, reinforcing a side of an interfloor barrier pillar, and drilling rock roofs for forced collapse; in FIG. 4 - section through
Б-Б на фиг. 3; на фиг. 5 - схема обрушени пород кровли при опускании щита. , Bb in FIG. 3; in FIG. 5 is a diagram of the collapse of the roof rocks when lowering the shield. ,
Подготовка пласта осуществл етс следующим образом.The formation is prepared as follows.
У вис чего бока пласта проводитс вентил ционный штрек 1, который у границы выемочного блока обиваетс наклонным ортом 2 со штреком 3. проведенным у лежачего бока пласта. С наклонного орта 2 заходками по 3 м производитс выемка монтажной камеры 4 дл монтажа щитового перекрыти 5. Транспортирование угл производитс вуглеспускные печи 6. Кровл 1 наклонного орта вл етс бортом межгори- зонтного барьерного целика 7, который укрепл етс анкерной крепью 8. МонтажAt the hanging side of the formation, a ventilation drift 1 is carried out, which at the boundary of the extraction block is entwined with an inclined unit 2 with a drift 3. conducted at the lying side of the formation. From the inclined unit wall 2, over 3 m runs, a mounting chamber 4 is removed for installation of the shield 5. The coal is transported by coal-blast furnaces 6. The roof unit 1 of the inclined unit is the side of the horizontal barrier pillar 7, which is fastened with anchor support 8. Installation
