【摘要】：為了準(zhǔn)確測(cè)定煤油氣共生礦井底板油型氣壓力值,在綜合分析黃陵礦區(qū)2煤底板油型氣特征的基礎(chǔ)上,提出了"測(cè)壓-抽采"一體化的底板油型氣壓力測(cè)定技術(shù),研究結(jié)果表明:2煤底板涌出氣體是典型的油型氣,在底板巖層中以游離態(tài)為主,分布具有不連續(xù)性,利用常規(guī)測(cè)壓方法測(cè)值嚴(yán)重偏低,采取"測(cè)壓-抽采"一體化的底板油型氣測(cè)定技術(shù)實(shí)測(cè)黃陵2號(hào)煤礦底板油型氣壓力為0.48~1.12 MPa,壓力恢復(fù)周期為0.18~8.0 h。
[Abstract]:In order to accurately measure the pressure value of oil type gas in bottom hole of kerosene gas cogeneration mine, on the basis of synthetically analyzing the characteristics of oil type gas of No. 2 coal bottom plate in Huangling Mining area, an integrated technology of "pressure measurement and extraction" is put forward for the determination of oil type gas pressure of bottom plate. The results show that the gas emitted from the coal floor is a typical oil-type gas, in which the free state is dominant, the distribution is discontinuous, and the value measured by the conventional pressure measurement method is seriously low. The oil type gas pressure of bottom plate of Huangling No. 2 coal mine is measured by "pressure measurement and extraction" integrated method. The recovery period of oil type gas pressure is 0.18 ~ 8.0 h. The pressure recovery period of oil type gas on bottom plate of Huangling No. 2 coal mine is 0.48 ~ 1.12 MPa,.
