摘要
矿井回采过程中小窑井筒等人工地质遗留体成为重要的不确定因素。为查明万杰煤业井田内2号煤层工作面内部小窑井筒赋存及积水情况,采用地面瞬变电磁、直流电法结合井下超前物探钻探综合探查技术进行了探测,较为准确地圈定了井下小煤窑采空破坏区范围。通过井下钻探验证,查明了井筒位置,为万杰煤业矿井安全采掘提供了地质资料。
Artificial geological remains such as small kiln shafts became an important uncertain factor in the process of coal mining.In order to find out the occurrence and water accumulation of small kiln shafts in the working face of No.2 coal seam in Wanjie Coal Mine,the ground transient electromagnetic method and direct current method combined with the comprehensive exploration technology of underground advanced geophysical exploration and drilling exploration were used to detect,and the scope of goaf damage area of small coal mines was accurately delineated.Through the underground drilling verification,the wellbore position was identified,which provided geological data for the safe mining of Wanjie Coal Industry.
