Abstract：According to the statistics and analysis of 366 pairs of main producing mines in North China, the regional distribution mainly is controlled by tectonics, the extrusion tectonic belts are the main distribution areas of tectonic coal, the edges of extensional tectonic belts are the second, the internals of extensional tectonic belts are the third. The level territory distribution mainly is controlled by the thickness of coal seam. The areas and layers that tectonic coal distribution is the best are the most serious of coal and gas outburst, the tectonic coal formed in the longitudinal buck-ling mainly is in the fold limbs, the tectonic coal formed in the faulting mainly is in the hanging-wall block, so the fold limbs and the hanging-wall block are more serious of coal and gas outburst, too.
