基于瞬变电磁法探究中高阶煤层瓦斯含量与视电阻率关系的试验
Transient electromagnetic exploration-based experiment on the relationship between the level of gas content and apparent resistivity in high rank coal seam
摘要
Abstract
In order to master the distribution law of the coal seam gas and reveal the relationship between gas content and apparent resistivity,the experiment combined the laboratory research on coal sample and resistivity and used transient electromagnetic method to study the correlation between apparent resistivity and gas content of coal seam,it has been detected for 18 times and 21 sets of the effective data were obtained.The research shows that there is a negative correlation between apparent resistivity and gas content of coal seam,when the gas content increased by 1 m3/t,the apparent resistivity decreased by 6.6％ to 20％,the determination coefficient was between 0.621 9 and 0.753 1 at the same time,it shows that the apparent resistivity of coal seams has a high degree of explanation to the coal seam gas content,the method can be used to detect the content and the distribution of coal seam gas with the similar geological condition.关键词
