Изобретение относитс к горной промышленности и может быть использовано при разработке пологих угольных пластов.The invention relates to the mining industry and can be used in the development of flat coal seams.
Известен способ разработки пологих угольных пластов при панельной подготовке шахтного пол , включающий проведение откаточных и вентил ционных штреков, наклонных выработок, выемочных штреков и последующую отработку выемочных столбов f .There is a known method for developing flat coal seams for panel preparation of a mine floor, which includes carrying out haulage and ventilation drifts, inclined workings, excavation drifts and the subsequent development of excavation columns f.
Известен также способ разработки пологих угольных пластов, включающий проведение откаточного, вентил ционного , промежуточного штреков и выемочных ходков и отработку подготовленных столбов очистными забо ми по восстанию .There is also a known method for developing flat coal seams, which includes carrying out haulage, ventilation, intermediate drifts and excavation walkways, and working out the prepared pillars with clearing holes for the uprising.
Однако оба указанных способа недостаточно эффективны в определенных горно-геологических услови х.However, both of these methods are not effective enough in certain geological conditions.
Цель изобретени - повышение эффективности разработки.The purpose of the invention is to increase the efficiency of development.
Поставленна цель достигаетс тем что очистные работы ведут одновременно в выемочном столбе между промежуточным и откаточным штреками и в выемочном столбе между ветил ционным и промежуточным штреками с разрывом в один столб, причем промежуточныйThe goal is achieved by the fact that the cleaning work is carried out simultaneously in the extraction column between the intermediate and backwater drifts and in the extraction column between the vetilization and intermediate drifts with a one-column break, and an intermediate
i. i.
штрек провод т в обрушенных и консолидированных породах выработанного пространства выемочных столбов.the drift is conducted in the collapsed and consolidated rocks of the excavated space of the excavation pillars.
На чертеже представлена обща схема ведени горных работ.The drawing shows a general mining scheme.
Способ заключаетс в следующем.The method is as follows.
На верхней границе горизонта провод т откаточный штрек 1, на нижней 0 вентил ционный штрек 2, а между ними - выемочные ходки 3-5. Отработку крыла начинают в двух первых стол .бах спаренными лавами по восстанию при пр моточном нисход щем проветрива5 нии с подачей подсвежающего воздуха походкам 3,-5.После отработки этими лавами половины запасов двух выемочных столбов очистные работы ведут одновременно в выемочном столбе A haulage drift 1 is conducted at the upper horizon, a ventilation drift 2 is drawn at the lower horizon, and between them are excavation steps 3-5. In the first two tables, the wing begins to be tested by paired lavas after the uprising with direct downward ventilation with supply of suction air to gaits 3, -5. After these half of the stocks of the two stocks of the two extraction columns are completed, the cleaning works are carried out simultaneously in the extraction column
0 между промежуточным штреком 6 и откаточным штреком 1 лавой 7, и в выемочном столбе между вентил ционным штреком 2 и промежуточным штроком 6 лавой 8 с разрывом в один выемочный 0 between the intermediate drift 6 and the haulage drift 1 of lava 7, and in the extraction pole between the ventilation drift 2 and intermediate drift 6 of lava 8 with a gap of one
5 столб. Промежуточный штрек прсвод т в разгруженном от горного давг.ени выработанном пространстве выемочных столбов. По промежуточному штрзку из лавы 7 вьщают исход щий воздух. Вы0 дачу исход щего воздуха из лавы 85 pillar The intermediate drift is located in the developed space of the excavation pillars unloaded from the mountain pressure. According to the intermediate strip, exhaust air is drawn out of lava 7. You give the outgoing air from the lava 8
