Description
(5) СПОСОБ ДЕГАЗАЦИИ ВЫРАБОТАННОГО ПРОСТРАНСТВА(5) METHOD OF DEGASING THE DEVELOPED SPACE
1one
Изобретение относитс к горной промышленности и может примен тьс при дегазации угольных шахт, в частности, при столбовой системе разработки.The invention relates to the mining industry and can be applied in the degassing of coal mines, in particular, in the pillar mining system.
Известен способ дегазации выработанного пространства при столбовой системе разработки с помощью трубопровода со свечой на конце, оставл емого в погашаемой части выработки Г ЗНедостатком этого способа вл етс то, что отсос газа производитс только на одной свече и отсутствует регулирование концентрации отсасываемого метана на ней.The known method of degassing the developed space in a pillar-based development system using a pipe with a candle at the end left in the redeemable part of the output. The disadvantage of this method is that gas is sucked only on one candle and there is no regulation of the concentration of methane sucked on it.
Наиболее близким к предлагаемому вл етс способ дегазации при сплошной системе разработки с помощью дегазационного трубопровода с отростками, оставл емыми в выработанном пространстве. Отростки включаютс в работу на рассто нии 30ЛО м от лавы, причем в работе посто нно наход тс два-три отрост , ка 2,The closest to the present invention is a degassing method with a continuous development system using a degassing pipeline with spikes left in the developed space. The processes are included in the work at a distance of 30L m from the lava, and two or three processes, ka 2, are constantly in operation.
Недостатки этого способа заклюThe disadvantages of this method are:
J чаютс в том, что газ отсасывают с низкой концентрацией метана, а при столбовой системе невозможно управл ть работой отростков дл отсоса газа с высокой концентрацией меto тана.J are found in the fact that the gas is sucked off with a low concentration of methane, and with a pillar system it is not possible to control the processes of the processes for the suction of gas with a high concentration of methane.
Цель изобретени - повышение эффективности дегазации и извлечение газа с высокой концентрацией ме-. тана.The purpose of the invention is to increase the efficiency of degassing and gas extraction with a high concentration of me-. tana.
