【摘要】 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.更多还原

【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,epigenetic 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 seismic exploration and drilling data,erosion zone was drawing a circle in unmined,for mine gas outburst(spray)prediction and prevention provides a basis.更多还原
