Abstract: Gujiao coal mining area is rich in coal resources．To identify the element parameters， sedimentary
environment and source of sediments in this area，not only can provide information for studying the development
of geological movement，but also guarantee the safe mining of coal mines．According to the Gujiao mining area
coal bearing strata in the mudstone samples for chemical detection， the research showed that the high field
strength elements and trace elements in the study area and lithophile elements content than the content in the
upper crust，and close to the pro content of iron and chalcophile elements and light rare earth elements in the
crust，and are enriched in hree phenomenon in the rare earth elements．According to Sr /Cu， V /( V + Ni) and
other indicators can be judged at the time of dry climate，the overall performance of the transitional sedimentary
environment reducing anaerobic environment in sedimentary facies， and the formation of mudstone source in
clastic sediments，also found that the Shanxi group also contains some granite material，which indicated that the
provenance of coal the Department should be in the active continental margin and continental contact
