针对新景矿3号煤层冲蚀带较易引发瓦斯突（喷）出的特殊情况，对煤层段岩性组合特征进行了分类研究．认为在构造破坏不甚严重的情况下，后生冲蚀导致的煤层段岩性组合的明显差异是矿井瓦斯突（喷）出频发的主要控制因素之一．在详细研究已采区冲蚀带物性响应特征和钻孔、采掘工程揭露，理清冲蚀带宏观分布特点的基础上，依据三维地震勘探和钻孔资料对未采区冲蚀带进行了圈划，为矿井瓦斯突（喷）出预测及防治提供了依据．

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.
