Geological Features of Panyi Coal Mine Based on Gas Occurrence Geological Tectonic Gradual Control Theory

According to the coal gas occurrence geological tectonic gradual control theory, the gas distribution characteristics and occurrence state affected by geological structure are controlled gradually from large to small. Regional geological structure is controlled by plate tectonics, mining areas and mines controlled by regional geological structure, mining working face controlled by mining areas and mines geological structure. Taking Huainan Panyi Coal Mine as an example, based on the geological analysis, regional geological structure controls the Huainan coalfield structure distribution, and then the structural characteristics of coal field control F₄ and F₅ faults distribution in Panyi Coal Mine, F₄ and F₅ fault control faults distribution of the whole mine faults and practical mining working faces.
