石炭—二叠纪地层是河南省主要含煤地层。作者对该含煤地层的含煤性研究是建立在煤层对比的基础上。该文阐述了煤层的层数、厚度、结构变化以及煤层的可采程度等含煤性特征。对于煤层可采程度评价，划分为：可采、局部可采、偶尔可采和不可采等组别；对于煤田和矿区可采程度评价，划分为普遍可采、基本可采、零星可采和非可采等组别。
The Carboniferous-Permian strata are the major coal-bearing formations in Henan Province. The author of coal-bearing strata containing coal is based on the comparison of coal seams. This paper describes coal seam characteristics such as layer number, thickness, structure change and coal seam recoverability degree. For the evaluation of coal seam recoverable degree, it can be divided into the following groups: recoverable, locally recoverable, occasional recoverable and non-recoverable. For the recoverable degree evaluation of coalfields and mines, the recoverable degree can be divided into general recoverable, basic recoverable, sporadic recoverable Non-recoverable groups.
