通过瞬变电磁法正演计算东胜煤田火烧区在不同充水情况下的信号响应特征,得出充水火烧富水区主要表现为低阻的特性。利用该结论对东胜矿区某矿探测成果进行定性解释和评价,根据后期钻孔验证较准确的情况,认为该地区利用瞬变电磁法探测煤层火烧富水区可以以低阻区为解释目标。结合磁法探测,可以较准确地探查煤层火烧富水区的范围,为煤矿安全开采提供科学依据。
Through transient electromagnetic method forward calculation, the signal response characteristics of Dongsheng coalfield under different water-filling conditions were obtained. It is concluded that the water-rich area of water-filling is mainly characterized by low resistance. According to the more accurate verification of later drilling, it is considered that the detection of the rich water area by transient electromagnetic method in this area can be explained by the low resistivity zone. Combined with magnetic detection, the scope of the firewater-rich water area can be probed more accurately, which provides a scientific basis for the safe mining of coal mines.
