【摘要】 利用三维地震勘探方法进行精确定位,瞬变电磁、电测深法综合解释验证的方法,对潞安集团司马矿第四系含水层组底部粘性土隔水层缺失形成的"天窗"区进行探测,并结合区域水文地质规律及矿井水文地质条件,对其富水性进行解释。首先利用"天窗"区内有无反射波的特性圈定其位置以及深度,再用对电阻率变化反应灵敏,分层明显的瞬变电磁法进行平面控制,然后用电阻率测深法进行深度控制,最终确定"天窗"的分布位置。更多还原

【Abstract】 By the use of 3D seismic prospecting exact locating,transient electromagnetic and electric sounding integrated interpretation carried out the detection of "scuttle" formed by hiatus of Quaternary aquifers’ bottom clayey confining bed in Sima coalmine,Luan Coal Group,combined with regional hydrogeological features and mine hydrogeological condition interpreted water yield property.Firstly using character of no reflection wave in "scuttle" area cycled out its position and depth,then used characters of sensitive responses on resistivity variation and transient electromagnetic method obvious layering carried out planar control,and then resistivity sounding depth control,finally "scuttle" distribution is located.更多还原
