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 view of the special situation that the erosion zone of Xinjing Mine No. 3 seam is more prone to gas outburst (outburst), the lithologic characteristics of the coal seam are classified and studied. Is one of the main controlling factors for gas burst (jet) outburst in coal mines.In the detailed study of the physical response characteristics and drilling of the eroded zone in the mined area, the excavation project exposes and clarifies the erosion Based on the characteristics of macroscopic distribution and the three-dimensional seismic exploration and drilling data, the erosion zone of the non-mining area was delineated, which provided the basis for the prediction and prevention of gas outburst in coal mine.
