综合物探方法在煤矿水文地质勘查中的应用

摘要

In allusion to issues of uncertain hydrogeological condition etc. in a coalmine, Yuzhou, Henan, have carried out seismic pros⁃pecting combined with TEM method. To ensure the interpreted results can be mutually corroborated, 4 coincident lines perpendicular to strata strike have been laid out. Taking the DZ03 seismic time section and TEM03 apparent resistivity section as example, according to their physical characteristics carried out subsided column and fault interpretations. The result has shown that interpretations of the integrated prospecting are highly consistent. Through the method, 1 subsided column and 8 fault complexes have been interpreted. Based on fault position and water rich area distribution have inferred large area water rich zones to the north of F 3 and F5, especially karst water extremely developed on fault intersections and connected from top to bottom. Besides, subsided columns have strong water yield property. Rather large area medium water yield property zones have existed to the north of faults F3 and XF2.%针对河南省禹州某煤矿区水文地质条件不明等问题，采用地震和瞬变电磁法相结合的方法进行勘探。为保证解释结果相互印证，在垂直于地层走向上布设了4条重合测线，并以其中的DZ03地震时间剖面和TEM03视电阻率断面图为例，依据其物理特征分别对陷落柱与断层进行了解释。结果表明，二种方法在解释异常位置、深度、形态及富水性等方面高度吻合。利用该方法解释矿区存在1个陷落柱，8条组合断层。根据断层的位置及富水区分布情况，推断F3和F5以北，富水性强且面积较大，特别在断层交汇部位岩溶水极其发育，且上下连通，另外陷落柱具有强富水性；F3以北和兴F2以西存在较大面积的中等富水区。
