(54) СПОСОБ ОПРЕДЕЛЕНИЯ МЕТАНОЕМКОСТИ УГЛЕЙ(54) METHOD FOR DETERMINING COAT METHANE PAPER

1one

Изобретение относитс  к способу определени  газоемкости ископаемых углей и может быть использовано научно-исследовательскими и производственными лаборатори ми, провод щими изучение газоносности угольных пластов и свойств угл , как коллектора газа.The invention relates to a method for determining the gas capacity of fossil coal and can be used by research and production laboratories that study the gas content of coal seams and the properties of coal as a gas collector.

Известен объемный способ определепи  сорбционной метапоемкости углей с сохранением в них природной влажности, заключающийс  в том, что образец угл , без предварительной его дегазации, донасыщаетс  метаном до давлений пор дка 60-70 ата. Иосле установлени  сорбционного равновеси  производ тс  выпуски отдельных замеренных порций газа и с фиксацией в каждом случае равновесного давлени . Затем проводитс  дегазаци  угл  с целью извлечени  всего оставшегос  газа в угле.A known volumetric method for determining the sorption meta-capacity of coal while retaining the natural moisture in it, is that the sample of coal, without prior degassing, is saturated with methane to pressures of the order of 60-70 atmospheres. After the sorption equilibrium has been established, the individual measured portions of gas are emitted and fixed in each case of the equilibrium pressure. Then coal degassing is carried out in order to extract all the remaining gas in the coal.

Ири дегазации угл , содержащего влагу, паличие вакуума и повыщенной температуры создает услови , при которых влага углей переходит в пар, который, попада  вместе с газом в замерную часть установки, приводит к завышению количеств последнего. В результате величина сорбционной газоемкости природного угл  оказываетс  выше действительной .The degassing of coal containing moisture, vacuum and increased temperature conditions creates conditions under which the moisture of the coal passes into steam, which, together with gas, enters the metering part of the installation, leading to an overestimation of the amount of the latter. As a result, the magnitude of the sorption gas intensity of natural coal is higher than actual.

Цель изобретени  - разработка способа определени  метаноемкости углей, который позволил бы получить истипные величиныThe purpose of the invention is to develop a method for determining the methane capacity of coal, which would allow to obtain the typical values

Эта цель достигаетс  путем поглощени  вод ных паров каким-либо поглотителем, например ангидроном Mg(ClO4) з. в процессе дегазации угл .This goal is achieved by absorbing water vapor by an absorber, for example, Mg (ClO4) anhidron. in the process of degassing coal.

Последующа  дегазаци  проводитс  таким образом, что влага, содержаща с  в угле и переход ща  в пар при наличии вакуума и повыщенной температуры,measured portions of gas with fixing ravosvesny pressure. The subsequent degassing is carried out in such a way that the moisture contained in the coal and passing into steam in the presence of vacuum and elevated temperature,
