Description

(54) СПОСОБ ПРОВЕДЕНИЯ ГОРНОЙ ВЫРАБОТКИ ПО ВЫБРОСООПАСНОМУ ПЛАСТУ(54) METHOD FOR CARRYING OUT MINING ON EMERGENCY LAYER

1one

Изобретение относитс  к горному делу и может быть использовано при проведении выработок по выбросоопасному угольному пласту смешанным забоем.The invention relates to mining and can be used in carrying out workings on outburst coal seam with a mixed bottom.

Известен способ горной выработки, включающий Образование по периметру выработки в направлении ее подвигани  сплошной ш,ели и выемку породы I.There is a method of mining, including Education around the perimeter of production in the direction of its progress solid w, spruce and excavation of rock I.

Недостатком этого способа  вл етс  наличие выбросов при образовании в выбросоопасной зоне.The disadvantage of this method is the presence of emissions during formation in the outburst zone.

Наиболее близким к предлагаемому по технической сущности и получаемому- результату  вл етс  способ проведени  выработки , включающий бурение скважин, сбивание их между собой по линии, параллельной забою выработки, многократным внутршиассивным гидроударом 2.The closest to the proposed technical essence and the result obtained is the method of carrying out the development, including drilling wells, knocking them together with each other along a line parallel to the bottom of the generation, with multiple internal hydraulic shock 2.

Недостатком данного способа  вл етс  возможность по влени  выбросов при бурении скважин по . углю и при сбивании скважин внутримассивным гидроударом.The disadvantage of this method is the possibility of emissions during drilling. coal and when knocking wells intramassive hydraulic shock.

Цель изобретени  - повышение надежности и безопасности проведени  работ по выемке-угл ./The purpose of the invention is to improve the reliability and safety of the work on the excavation-coal.

Поставленна - цель достигаетс  тем, что согласно способу, включающему бурение скважин, сбивание их между собой по линии , параллельной забою выработки, выемку угл , скважины бур т с породной части 5 забо  выработки до контакта с пластом, усть  скважин перекрывают вентил ми с отводными устройствами, при этом сбивание скважин между собой по линии, параллельной забою выработки, производ т выбурило ванием котловых полостей, соедин ющихс  между сабой.The goal is achieved by the method, which includes drilling wells, knocking them together in a line parallel to the bottom of the mine, coal mining, wells are drilled from the rock part 5 of the mine bed before contact with the reservoir, and the wellheads are blocked with outlets At the same time, knocking down wells between each other along a line parallel to the downhole of production is carried out by drilling the boiler cavities connecting between the sabi.

На фиг. 1 показана горна  выработка-, проводима  по пласту, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the hearth development, carried out along the seam, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

J5 Способ осуществл етс  следующим образом .J5 The method is carried out as follows.

Через породную толщу до пересечени  с угольным пластом I бур т скважины 2 в направлении подвигани  выработки, усть  этих скважин перекрывают вентил ми с водными устройствами 3, через которые производ т дегазацию массива, начина  с крайних скважин при помощи расширителей образуют котловые полости 4, которые соедин ют между собой последовательно такимThrough the rock stratum before intersection with the coal seam, the first bore of borehole 2 in the direction of production advancement, the mouth of these wells is blocked with valves with water devices 3 through which the array is degasified, starting from the extreme bore holes with the help of expanders form the boiler cavities 4, which connect between each other in series

образом, что по линии шага очередной заходки отдел ют от массива угольного пласта блок угл , при этом разбуривание котловых полостей производ т с вод ной промывкой или воздушной продувкой, о соприкосновении полостей друг с другом суд т по выходу буровой мелочи из соседней с разбуриваемой скважиной. В отделенном от угольного массива блоке угл  выбросоопасность снижаетс  вследствие интенсивной дегазации и внутримассивного отжима угл . После разбуривани  котловых полостей и производства дегазации угольного пласта , когда истечение метана из скважины прекрашаетс , извлекают отводные устройства , размещают в них зар ды ВВ и производ т выемку угл  на величину шага заходки буровзрывным способом, затем выемку породы, при этом бока выработки в местах выхода пласта тщательно закрывают зат жками.In other words, the coal block is separated from the coal seam along the step line of the coal bed, and the boiler cavities are drilled with water flushing or air blowing, and the cavities are in contact with each other by the exit of the drilling fines from an adjacent well drilled. Separated from the coal mass of the coal block, the out-of-danger is reduced due to the intensive degassing and intramassive pressing of the coal. After drilling the boiler cavities and degassing the coal seam, when methane outflow from the well ceases, extraction devices are removed, charges of explosives are placed in them, and coal is excavated by the step of drilling in the drilling and blasting method, then the rock is excavated. the reservoir is carefully closed with a stitch.

Преимущество предлагаемого способа заключаетс  в том, что повыщаетс  безопасность работ при проведении выработок по выбросоопасным пластам, при производстве противовыбросных меропри тий снижаетс  трудоемкость работы, так как выполн емые операции по предотвращению внезапных выбросов совпадают с технологическими операци ми по проведению выработок .The advantage of the proposed method is that the safety of work increases when carrying out workings on outburst formations, and when producing anti-blowout measures, the laboriousness of work is reduced, since the performed operations to prevent sudden outliers coincide with the technological operations for conducting workings.
