Description
Изобретение относитс к горной промыш- .н:инос 1и и нредназиачсно дл разработки ш-сьма топких крутых пластов.This invention relates to the mining industry: inos 1i and is not necessary for the development of a wider steep seam.
Цель изобретени - повышение эффективности разработки за счет ликвидации угл в межскважинных целиках и уменьшени затрат на бурение скважин.The purpose of the invention is to increase the development efficiency by eliminating coal in the interwell wells and reducing drilling costs.
Способ осуществл етс следующим образом .The method is carried out as follows.
По простиранию пласта провод т вентил ционный и откаточный штреки. Перпендикул рно штрекам бур т скважины и нарезают столбы через каждые 4-15 м по простиранию пласта в зависимости от устойчивости пород кровли. В скважины пропускают два каната диаметром 15-20 мм. К концам канатов прикрепл ют канатную или цепную пилу и с помощью приводной лебедки, установленной на вентил ционном штреке, сообщающей пиле поступательно-возвратное движение с щагом Ь- 2 м, приступают к отбойке угл . Подпиленный уголь под вли нием горногоAlong the strike of the formation, a ventilation and haulage drifts are conducted. Perpendicular to the drifts of the drill hole and pillars are cut every 4–15 m along the strike of the reservoir, depending on the stability of the roof rocks. Two ropes with a diameter of 15-20 mm are passed through the wells. A rope or chain saw is attached to the ends of the ropes and, using a drive winch mounted on a ventilation drift, telling the saw to move forward and backward with the L-2 m clamp, the coal is started. Charred coal under the influence of mountain
давлени гравитационных сил обрушаетс транспортабельными кусками и временно ма- газинируетс . Учитыва коэффициент разрыхлени , уголь, постепенно выпускают через люки. Управление кровлей в столбах производ т путем полной закладки выработанного пространства.The pressure of gravitational forces is collapsed by transportable pieces and temporarily gassed. Taking into account the coefficient of loosening, coal is gradually released through the hatches. Roof management in the pillars is carried out by fully laying out the goaf.
Выработанное пространство при этом ограждаетс от рабочей полосы дерев нными желобами, изготовленными из досок длиной 2-3 м, толщиной 4-6 см, которые опускаютс из вентил ционного штрека по канату, нат нутому вдоль всей длины столба между откаточным и вентил ционными щтреками, что позвол ет прикрепить к концам этих канатов цепную или канатную пилу с последующей выемкой очередного столба. Причем выемку столбов производ т через один, что и приводит к исключению потерь угл в целиках, уменьшению трудозатрат по бурению скважин в два раза.At that, the developed space is protected from the working strip by wooden grooves made of boards 2-3 m long, 4-6 cm thick, which are lowered from the ventilation drift along the rope stretched along the entire length of the column between the haulage and ventilation plugs, which allows you to attach to the ends of these ropes a chain or wire saw with the subsequent excavation of the next pole. Moreover, the removal of the pillars is carried out through one, which leads to the exclusion of the loss of coal in the pillars, reducing the labor costs for drilling wells by half.
