摘要
大水煤矿水文地质情况复杂 ,运用瞬变电磁法进行勘察 ,根据获得不同时间道的电磁场信息反映不同深度介质的地电特征 ,查清了测区内涌水通道及富水部位在立体空间上的分布情况。证实了本区地表河流和池溏水与地下水的补给关系。提出了预防煤田涌水的措施。
Transient Electromagnetic Method can be used to prospect the complex geological situation of water rich coal fields.According to the obtained electromagnetic information of different Time trance,which can indicate the geoelectric features of the medium of different depth,the distribution of the water gushing channelway and water rich partions in the target area is found out.The alimentation relationship between the surface water and the subsurface water is proved.At last,some precautionary measures against the water gushing in coal field are put forward.
