Description
Изобретение может быть использовано при проходке, например, комбайнами пластовых выработок с высокой газоносностью.The invention can be used when driving, for example, by combines of formation workings with high gas content.
Известен способ проветривани глухих или затопленных выработок с применением горизонтальных или слабонаклониых скважин, по юторым за счет общешахтной депрессии движетс исход ща воздушна стру }.There is a known method of ventilating deaf or flooded workings using horizontal or weakly inclined boreholes, the outward air stream is moving along the major depression due to a general mine depression.
Недостатком этого способа вл етс невозможность его применени при проходке по газоносным пластам парных выработок значительной прот женности.The disadvantage of this method is the impossibility of its use when penetrating gas-bearing formations of dual workings of considerable length.
Известен также способ проветривани тупиковых парных выработок, проводнмых по газоносным пластам, заключающийс в подаче свежего воздуха в забой по трубам и отводе загр зненного воздуха по выработке (2.There is also known a method for ventilating dead-end paired workings conducted through gas-bearing formations, which consists in supplying fresh air to the bottomhole through pipes and discharging polluted air through generation (2.
Недостатком этого способа вл етс мала эффективность проветривани и невозможность создани безопасных условий при одновременной работе в двух забо х.The disadvantage of this method is the low efficiency of ventilation and the impossibility of creating safe conditions when working simultaneously in two holes.
Цель изобретени заключаетс в повышении эффективности проветривани и созданий безопасных условий при одновременной работе в двух забо х.The purpose of the invention is to increase the efficiency of ventilation and to create a safe environment when working simultaneously in two faces.
Цель достигаетс тем, что загр зненный воздух отвод т из забо отстающей выработкнThe goal is achieved by the fact that polluted air is discharged from the lagging behind
по скважине, еосдйийющей забой отстающей выработки с передовой вентил ционной сбойкой , по отношению к забою отстающей гориой выработки, и по отсасывающему трубопроводу , соединенному со скважииой и проложеиному но передовой вентил ционной сбойке и далее по трубопроводу, проложеииому по выработке с опережающим забоем и соедииеиному с веитил тором местносо проветриваии .on the well, behind the bottom of the lagging development with advanced ventilation system, in relation to the bottom of the lagging development, and through the suction pipeline connected to the well and the newly advanced ventilation assembly and further along the pipeline, which has been developed, with advanced equipment and advanced ventilation system and further along the pipeline, which has been completed, with advanced software and advanced ventilation system and further along the pipeline, which has been completed, with advanced software and advanced ventilation system and further along the pipeline, which is ahead of schedule, the advanced ventilation system is installed and further along the pipeline, which is ahead of schedule, the advanced ventilation system is installed and further along the pipeline, which has been completed, the advanced section and the lateral exhaust ventilation system and further along the pipeline, which is laid out with advanced equipment, and the advanced section of the lateral ventilation system and then through the pipeline that has been developed, with advanced software and advanced ventilation system and further along the pipeline, which is ahead of schedule, the advanced ventilation system is connected to the secondary section, and then along the pipeline, which is ahead of schedule, the advanced ventilation system is connected to the secondary section and further pipelines that are equipped with the advanced section of the exhaust ventilation system by a torus of local airing.
На чертеже изображена схема проветрива10 ии при проходке парных вЫрабстж.The drawing shows a diagram of the airing 10 and during the penetration of paired virabstzh.
Способ проветривани тупиковых парных выработок осуществл етс следу мщнм образом .The method of airing the dead-end paired workings is carried out in the following way.
Дл проветривани выраоотки i с опережающим забоем в отстающей выработке 2 To ventilate growth i with a leading downside in lagging development 2
5 устанавливают 2-3 става с вентил торами 3, которые прокладывают через сбойку 4. Отсасывающий трубопровод 5 дл вывода отработаниого воздуха из отстающей выработки 2 проходит через передовую сбойку 6, затем по 0 выработке 1 с опережакмцйм забоем. На конце трубопровода помещен вентил тор 7.5, 2–3 staves with fans 3 are installed, which are run through the coupling 4. The suction pipe 5 to discharge the exhaust air from the lagging generation 2 passes through the forward coupling 6, then 0 through the output of 1 s of the bottom. At the end of the pipeline placed the fan 7.
В цел х повышенн эффективности проветривани отстающей выработки 2 перед сбойкой 4 устанавливают вентил тор 8, который .по прорезиненному ставу иагиетает в забойIn order to improve the ventilation efficiency of the lagging generation 2 before the mounting 4, a fan 8 is installed, which, according to the rubberized bed, is installed in the face
этой выработки свежий воздух, создава непосредственно в призабойном пространстве тур. булентность воздушного потока.this production fresh air, creating a tour directly in the bottomhole space. air flow boiling.
Предлагаемый способ проветривани тупиковых парных выработок позвол ет в два раза повысить темпй проведени парных выработок и коэффициент использовани комбайнов во времени, ликвидировать непроизводительные затраты труда и времени на монтаж-демонтаж и перегон комбайна из одного забо в другой, снизить себестоимость проходки горных выработок на 35-40% при обеспечении безопас ых условий работы.The proposed method of airing the dead-end paired workings makes it possible to double the rate of conducting double workings and the utilization rate of harvesters in time, to eliminate the unproductive expenditure of labor and time for installation, disassembly and removal of the combine from one slab to another, to reduce the cost price of mining workings by 35 40% while ensuring safe working conditions.
