Gas outburst （spray） of epigenetic washout out of control in No. 3 coal seam of Xinjing coal mine
Abstract：In No. 3 coal seam of Xinjing coal mine,erosion is easy to cause gas outburst（spray） , in this case, do a classfication research on rock properties of seam section. When structural damage is not serious , epige- netic erosion led to the rock properties of seam section difference is mine gas outburst（spray） frequent one of the main control factors. In a detailed study of the mining areas erosion with physical response characteristics, drilling and mining engineering to expose, clear distribution of erosion characteristics, based on the 3D seis- mic exploration and drilling data , erosion zone was drawing a circle in unmined, for mine gas outburst（spray） prediction and prevention provides a basis.
