摘　　要：绘制3煤层顶底板砂岩厚度等值线图和沿工作面的首采区沉积断面图,并利用瞬变电磁法来探测首采区,根据地下岩层电性特征绘制沿首采面上平巷、中轴及下平巷的电法勘探断面。通过分析所绘制图件的特征来总结低阻异常与砂体厚度之间的关系,并预测出山西组3煤顶底板砂岩水和太原组三灰水涌水量,最终预计首采区的总涌水量。Drawing the 3 coal seam roof and floor sandstone thickness contour map and the sedimentary section along the first mining area. Then detecting the first mining area with the transient electromagnetic method and according to the electrical characteristics of underground rock to draw the electrical prospecting section of upper gangway, middle axle and lower gangway of the first mining area. By analyzing the characteristics of thees maps,summarizing the relationship between low resistivity anomaly and sand body thickness, and predict the water inflow of Shanxi 3 coal seam top and floor sandstone water and Taiyuan three ash water. Finally, the total water inflow in the first mining area is expected.
