The study area covers 4 mines producing sclerotia algal type coal in Hunyuan,Shanxi Province.the study combined both coal petrologic and geochemical methods indicated that the sclerotia algal coal is physically and chemically different from humic coal apparently,the forming environment is mainly controlled by pH,Eh and organic content,in which Pila Alginite and Reinschia Alginite are highly dominated.

运用煤岩学和地球化学方法，对中国山西浑源等 4个典型的菌藻类煤进行了综合研究，结果表明，菌藻类煤在物理、化学组成和特性上与腐植煤有明显的区别；其形成环境主要受 p H、Eh值和有机质含量的制约，其中皮拉藻和轮奇藻具有含量高、生存时间长的特征；并在此基础上对菌藻类煤作了成因分类

The coal tar pitch powder was used with each of 22 kinds of dispersants prepared coal tar pitch water slurry,and 6 kinds of dispersants were selected to prepare coal tar pitch water slurry with the high temperature coal tar pitch powder which has a softening point of 105℃.

采用冷冻粉碎的方法将软化点为90℃的中温煤沥青制得粒度≤200目的煤沥青粉后，再与22种分散剂制备煤沥青水浆，从中筛选出6种成浆性好的分散剂再与软化点为105℃的高温煤沥青粉制备煤沥青水浆，结果表明中温煤沥青粉比高温煤沥青粉更易制得稳定性好的煤沥青水浆。
