Description
Изобретение относитс к горной . промьпютенности и предназначено дл Рс13работки крутых пластов столбами по восстанию.The invention relates to mining. industrialized and designed for P13 working steep seam pillars for the uprising.
Известен способ разработки мощнцх крутопадающих пластов Г1.There is a method of developing powerful steeply dipping seams G1.
Однако способ недостаточно эффективен .However, the method is not effective enough.
Известен способ разработки крутых пластов столбами по восстанию, включающий проведение скважин, подрубку столбов угольной пилой и выпуск отбитого угл 2, I Однако способ характеризуетс большим выходом негабарита и достаточнонизкой производительностью труда,There is a known method of developing steep seams with pillars for rebellion, including drilling wells, cutting pillars with a coal saw and releasing repulsed coal 2, I. However, the method is characterized by a large yield of oversize and sufficiently low productivity.
Целью изобретени вл етс уменьшение выхода негабарита и повышение производительности труда.The aim of the invention is to reduce the oversize yield and increase productivity.
Поставленна цель достигаетс тем, что из провёденньи скважин в пласте прюрубают вертикальные щели на всю длину столба, а затем производ т . его подрубку.This goal is achieved by drilling vertical gaps along the entire length of the column from the wells in the reservoir and then producing them. his hemming
На фиг. 1 изображено выемочное поле, общий вид; на фиг. 2 - сечение А-А на фиг. li на фиг. 3 - сечение Б-Б на фиг. 1; на фиг. 4 - сечение на фиг. 1.FIG. 1 shows a notch field, general view; in fig. 2 is a section A-A in FIG. li in fig. 3 is a section BB in FIG. one; in fig. 4 is a sectional view in FIG. one.
Способ осуществл етс следующим образом.The method is carried out as follows.
Выемочное поле отрабатывают столбами по восстанию в направлении от границ 1 выемочного пол к участковому квермпагу 2. В первую очередь последовательно на всю длину выемочного пол отрабатывают первичные столбы 3 с оставлением между ними The excavation field is worked by the columns of the uprising in the direction from the boundaries 1 of the excavation floor to the precinct kwermpag 2. First of all, the primary columns 3 are sequentially for the entire length of the excavation floor, leaving them between
10 временных целиков 4. Дл отработки столба провод т скважины 5 у почвы Г пласта с конвейерного 6 на вентил ционный 7 штрек..Одну из скважин с конвейерного штрека расшир ют в 10 temporary pillars 4. For the development of the pole, wells 5 are drilled at the soil G of the reservoir from the conveyor 6 to the ventilation 7 drift. One of the wells from the conveyor drift is expanded into
15 дучку 8 и на рассто нии 4-6 м над конвейерным штреком столб подсекают от почвы до кровли пласта с помощью буровзрывных работ и таким образом создают, нависающий забой 9 столба. 15 Duchku 8 and at a distance of 4-6 m above the conveyor drift, the pole is cut from the soil to the top of the formation with the help of drilling and blasting operations and thus create an overhanging face of the 9th pole.
20 Дучку и нависающий забой креп т дерев нной и анкерной крепью.20 Duchka and overhanging face are secured with wooden and anchor lining.
Из скважин врубовой машиной 10 от почвы к кровле пласта прорубают вертикальные Щели 11 на всю ,длину From wells, the cutting-edge machine 10 cuts vertical to the top of the layer from the soil to the roof of the formation for the entire length
25 столба, затем столб, оконтуренный этими щел ми и нависающим забоем, подрубают по восстанию у почвы пласта угольной пилой 12; По мере подрубки уголь в нависающем забое обру30 шаетс и выпускаетс из камеры 13The 25 pillars, then the pillar, contoured by these gaps and the overhanging face, are hewn by rebellion on the soil of the stratum with a coal saw 12; As the hem is cut, the coal in the overhanging bottomhole is rimmed and released from chamber 13
