摘要
利用综合物探方法在河北省磨窝煤矿成功地探测出隐伏的富水古河道,并确定了水井的最佳位置和深度,解决了矿区水源问题.根据岩石电性特征,提出了判别含水层含水性强、中、弱的电参数标志,据此确定了古河道的走向及边界位置.反演时,由于地层薄,利用ρs曲线划分岩层效果不明显,改用激发极化率η_s测深曲线分层,并配合ρs进行综合反演,所得结果与实际地质层位比较吻合.
The buried water-rich palaeochannel, an underground water reservoir, in the vicinity of the Mowo Coal Mine, Hebei, was successfully delineated by using integrated geophysical exploration. Optimal Location of water-wells and their depth were also determined. Based upon electric properties of the rocks in that area, some discriminant guides for the water capacity of the water-bearing horizons were suggested by the author, and the strike and boundary of the palaechannel were thus determined. At the inversion of the resistivity sounding curves, water-bearing strata of small thickness are difficult to be distinctly distinguished. For this reason IP sounding curves were used and a combined inversion of resistivity and IP curves were made. The results are in comformity with the practical geological horizons.
