连阳煤田龙潭组分布较广,为该煤田主要含煤建造。由于它所处的构造部位和沉积环境的影响,使主要煤层硫的分布具有一定特点。关于连阳煤田龙潭组的划分和对比,目前尚有不同看法。一般将其划分为三部分:即下含煤段、中部海相层段和上含煤段。上含煤段含极不稳定煤层,多属不可采层;下含煤段含主要煤层11和10号煤,为局部可采煤层。下含煤段为本文的主要论述对象。本文试图从龙潭组主要煤层硫的分布特点及其与沉积环境的关系,提出初步看法。
Longtan Formation in Lian Yang Coal Field is widely distributed and is the major coal-bearing site in this coal field. Because of the tectonic site and sedimentary environment in which it is located, the distribution of sulfur in the main coal seams has certain characteristics. There are different opinions on the division and comparison of Longtan Formation in Lian Yang Coalfield. It is generally divided into three parts: the lower coal-bearing section, the middle marine section and the coal-bearing section. The upper coal-bearing section contains extremely unstable coal seams, which are mostly non-recoverable; the lower coal-bearing sections contain main coal seams No. 11 and No.10, which are locally recoverable seams. The lower coal section is the main object of this article. This paper tries to put forward some preliminary opinions on the distribution characteristics of sulfur in the main coal seams of Longtan Formation and its relationship with sedimentary environment.
