Research the gas geology conditions in Juye coal field,Shandong Province, China
Juye coalfield is a major coalfield in Shandong. With the progress of coal mine digging, the gas geology characteristics are more and more important for safety in production. Based on the analysis of gas geology characteristics, this paper first summarizes the affecting factors of gas occurrence, such as the coalfield structural distribution, the buried depth of coal bed, the operating range of magmatism, and then sums up the total characteristics of gas in Juye coalfield. The results are concluded that the geological environments of Juye coalfield are not good for gas occurrence, but at the central coalfield, the buried depth of coal seam is bigger, and the magma activity is stronger, furthermore the structures is not development in the overlying rock mass, so the gas occurrence conditions are relatively good. But at the other parts of Juye coalfield, a few of coal seam outcrops exist, and many open faults are development, alt which make the gas easy to be lost. So the gas occurrence conditions are not good in most parts of Juye coalfield.
