甲烷-空气混合物的爆炸危险性已成为采矿中日益严重的问题，因此，预先评估甲烷气体潜力对于安全和经济的矿井开发计划至关重要。作为煤矿健康和安全计划的一部分，矿务局开发了一种简单、廉价的测试方法，用于测量从勘探岩心中获得的煤样的甲烷含量。用直接法试验测定的单位重量煤的瓦斯含量可作为初步估计矿井通风要求的依据，并确定是否应考虑在开采前对煤层进行脱气。以表格形式总结了583次直接法试验的结果。这些结果包括15个州125个煤层的气体含量数据。
The explosion hazard of methane-air mixtures has become an increasingly serious problem in mining, and an advance assessment of methane gas potential is therefore essential for a safe and economic mine development program. As part of its coal mine health and safety program, the Bureau of Mines has developed a simple, inexpensive test to measure the methane content of coal samples obtained from exploration cores. The gas content of coal per unit weight as determined by the direct method test can be used as a basis for a preliminary estimate of mine ventilation requirements, and to determine if degasification of the coalbed in advance of mining should be considered. The results of 583 direct method tests are summarized in tabular form. These results include data on the gas content of 125 coalbeds in 15 states.
