【摘要】：为了准确测定煤油气共生矿井底板油型气压力值,在综合分析黄陵矿区2煤底板油型气特征的基础上,提出了"测压-抽采"一体化的底板油型气压力测定技术,研究结果表明:2煤底板涌出气体是典型的油型气,在底板岩层中以游离态为主,分布具有不连续性,利用常规测压方法测值严重偏低,采取"测压-抽采"一体化的底板油型气测定技术实测黄陵2号煤矿底板油型气压力为0.48~1.12 MPa,压力恢复周期为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,.
