Abstract:
The paper analyzes the tectonic evolution laws based on the dynamics of plate tectonics, and studies the tectonic control laws of gas occurrence combined with the gas content measured in the field; the results showed that the east west tectonic showed mainly as normal faults while the north south tectonic showed mainly as folds, and large geotectonic evolution led to low gas content of the whole mine field. The characteristics of difference from east to west, difference from north to south, and local anomaly was formed by regional hydrogeology conditions, roof and floor lithology, faults, folds, bedding shear and so on.
