任楼井田82煤层构造煤分布规律及其控制因素

Tectonic Coal Distribution Law and Control Factor of No.82 Seam in Renlou Minefield

  • 摘要: 为了查明任楼井田82煤层构造煤的分布特征及影响构造煤层分布的因素,利用钻孔测井曲线,结合井巷工程揭露情况,对82煤层各钻孔构造煤厚度进行识别、统计,并绘制构造煤层厚度等值线,在此基础上对82煤构造煤层的分布特征进行分析。分析结果表明:井田内构造煤普遍发育,井田南部构造区,构造煤较为发育,构造煤在煤体中所占的比例在80%左右;在中部构造区,构造煤厚度分布稳定;在北部构造区内受煤层厚度较薄的影响,构造煤厚度相对较薄。井田构造煤分布受褶曲构造、断裂构造与地应力综合因素的影响。

     

    Abstract: In order to find out the distribution features of the structure coal in No.82 seam of Renlou Minefield and the factors affected to the structure seam distrib ution, the borehole logging curves and the exposed conditions of the mine shaft and roadway engineering were applied to identify and count the structure coal thickness of each borehole in No.82 seam and to draw the thickness equivalent line of the structure seam.Based on the circumstances, the distribution features of No.82 structure seam were analyzed.The analysis results showed that the structure coal within the minefield was generally developed, the structure coal in the south structure block of t he minefield was well developed and the structure coal was taken about 80% in the total percentage of the coal seam.In the middle of the structure block, the distributio n of the structure coal thickness was stable.Within the north structure block, with the influence of the thin seam thickness, the thickness of the structure coal seam was relevantly thin.The structure coal distribution in the minefield was influenced by the comprehensive factors of the fold structure, broken structure and ground stress.
