【摘要】：在含水煤巖瓦斯壓力測(cè)定過(guò)程中,為了正確的獲得瓦斯壓力測(cè)定結(jié)果,通過(guò)理論公式的推導(dǎo)分析糾正了以往得出瓦斯壓力恢復(fù)曲線理論分析的不足,并由現(xiàn)場(chǎng)實(shí)測(cè)數(shù)據(jù)驗(yàn)證表明:當(dāng)測(cè)壓管中涌出的皆為瓦斯氣體時(shí),瓦斯壓力恢復(fù)曲線為類拋物線型,這種規(guī)律在眾多煤礦實(shí)地壓力測(cè)定中得到驗(yàn)證;當(dāng)測(cè)壓管中涌出的全是水時(shí),瓦斯壓力恢復(fù)曲線為近似的直線型;當(dāng)測(cè)壓管中涌出的是瓦斯和水的混合物時(shí),瓦斯壓力恢復(fù)曲線為拋物線和直線的復(fù)合曲線型。
[Abstract]:In the process of gas pressure measurement in water-bearing coal and rock, in order to obtain the gas pressure measurement result correctly, the deficiency of theoretical analysis of gas pressure recovery curve obtained in the past is corrected by deducing and analyzing the theoretical formula. It is proved by the field data that the gas pressure recovery curve is parabola when the gas is emitted from the pressure measuring pipe. This rule has been verified in many coal mine field pressure measurement. The gas pressure recovery curve is an approximate straight line when all the water is gushing out in the pressure measuring pipe, and the gas pressure recovery curve is a compound curve of parabola and straight line when the gas and water mixture is gushing out in the pressure measuring pipe.
