摘要
本文通过对贵州西部晚二叠世煤层分布的研究,介绍了晚二叠世煤层在龙潭早、中、晚期及长兴阶等各时期煤层层数、累积厚度、含煤率的时空变化特点,并着重指出各时期主要可采煤层的分布情况及富煤带(区)、富煤中心在沿海岸线上、下的过渡相区内随着时间的推移而逐渐向西迁移的规律。
This paper deals with the space -time distribution features of the deposited coalbed numbers, accumulated depths and coal -bearing ratios of the Late Permian coalbeds in different stages of Early, Middle and Late Longtan Periods and the Changxing period, etc. in wertern Guizhou and emphatically describes the distribution of the coalbeds capable of mining in different stages and the law that abundant coal zones and thier
centers gradually migrated westward within the transition phase areas up and down the coastline with the lapse of time.
