集气式和解吸法采测的煤层甲烷含量的比较

COMPARISON OF THE VALUES OF COALBED METHANE CONTENTMEASURED BY GAS COLLECTION AND DESORPTION METHODS

根据煤层甲烷的总体赋存规律，运用回归分析的方法，建立了淮南煤田某勘探区内煤层甲烷含量的集气式测值和解吸法测值与各自埋深之间的相关关系，继而对在同一深度处求得的两个回归值进行比较分析，得出了煤层甲烷含量的集气式测值与解吸法测值之间并不存在必然联系的结论。

The correlative relation was established between contents of methane,measured by gas collection and desorption methods,and the depth of coal seam in an exploration area in Huainan Coalfield by regression method on the basis of general rules of methane occurrence.Two regression values obtained at the same depth were compared.A conclusion was drawn that there was no necessary relation between the methane contents measured by these two methods,which provided a sufficient criterion for analyzing and collation of the methane data.
