Abstract:In view of the complex structure in the study area,tectonic position and tectonic zone with more display abnormal gas and coal and gas outburst (spray) of multiple,prone to wait for a characteristic.By applying theory of gas geology,the control of structure to coal seam gas occurrence and gas outburst (spray) and its regulation were studied.Studies show that "closed" compressional and shear structure of coal seam gas pressure preservation provides a good "sequestration effect", which is important factor to control the area of coal seam gas content being high and uneven distribution;Construction type,nature and combinations jointly control seam gas partition,zoning and sudden coal and gas (spray) the scope and probability.
