论地勘时期煤层瓦斯含量现场测定

Determination on the spot of coal seam gas-bearing capacity in Geological exploration period

论述了地勘时期煤层瓦斯含量现场测定的重要性,阐述了地勘时期煤层瓦斯含量现场测定的基本工作包括设备器具的准备、现场测定和记录,并从煤样密封罐的气密性、煤芯的钻取、瓦斯解吸速度的现场测定、气体体积校正、瓦斯损失量计算、记录和送样等方面探讨了地勘时期煤层瓦斯含量现场测定应注意的事项。

This paper analyzed the importance of determination on the spot of coal seam gas-bearing capacity in geological exploration period,the basic work like preparation of tools,determination on the spot and record were also demonstrated,and from aspects such as gas tightness of coal sample sealed tank,drilling to obtain the coal core,determination on the spot of velocity of gas desorption,gas volume correction,calculation of loss of gas,record,sample delivery,the matters need attention in determination on the spot of coal seam gas-bearing capacity in geological exploration period were discussed.
