Abstract
The occurrence state of methane is mostly controlled by coalfield geological structures. The coal-bearing strata at Qidong coalmine experienced many tectonic cycles since their formation. The gas content made by the complicated structural geologic system at the coalfield is very different, which is obviously higher on the north side of the Weimiao fracture belt than that on the south side and near itself. This thesis discussed the gas occurrence regularity based on the geometric characteristics of the geological structure and its regional tectonic evolution. This study can provide a foundation for coalfield exploitation and deal with coal and gas outburst.
