我国煤层气(煤矿瓦斯)计量标准研究

Research on Coalbed Methane(Coal Mine Methane)Measurement Standards in China

煤层气(煤矿瓦斯)计量是煤层气(煤矿瓦斯)抽采和通风瓦斯排放的重要环节,直接关系到甲烷的利用和排放。计量标准的完善与否决定了计量的准确度和精确度。本文对我国煤层气(煤矿瓦斯)计量标准体系现状进行研究,找出存在的问题,提出煤层气(煤矿瓦斯)抽采和通风瓦斯排放计量标准制定建议,有利于准确摸清我国煤炭领域甲烷排放量和利用量底数。

Coalbed methane(coal mine methane)measurement is an important link in CBM(CMM)drainage and emission of ventilation air methane(VAM),which is directly related to the utilization and emission of methane.The improvement of measurement standards determines the accuracy and precision of measurement.This paper studies the present situation of the CBM(CMM)measurement standard system in China,finds out the existing problems and puts forward suggestions for the formulation of measurement standards for CBM(CMM)drainage and VAM emission,which is conducive to accurately figure out the volume of methane emissions and utilization in the coal sector in China.
