【摘要】 本文实验研究了煤屑的瓦斯解吸规律,实验表明:煤屑的解吸瓦斯流量与煤层瓦斯含量、瓦斯压力密切相关,利用煤屑解吸瓦斯流量可准确测算煤层瓦斯压力和瓦斯含量,该方法具有测定速度快、简单易行、数据可靠等特点,可在现场推广应用.最后提出了利用煤屑解吸瓦斯流量测算煤层瓦斯压力和瓦斯含量的计算方法和计算公式.更多还原

【Abstract】 A research is carried out to study the regularity of methane emission from broken coal in the paper. The result indicates that the rate of methane emission from broken coal is strongly dependent on its content and pressure in coal. Finally the calculation method and formula of coal methane content and pressure are presented by using the emission rate from broken coal.更多还原
