摘要
为了确保东庞矿21209工作面的安全回采,查明工作面底板及外围一定范围内岩层富水性及工作面内隐伏导含水构造,采用瞬变电磁技术、温纳三级电测深技术、无线电波坑道透视及音频电透视综合物探方法,对工作面内部隐伏导、含水构造,尤其是隐伏导水陷落柱、断层和裂隙密集发育带进行探测。结果表明,在探测范围内共有3处相对低阻异常区,其中S1、S2异常为野青灰岩附近岩层破碎含水反应,YP1异常为岩层局部富水反应;2处地质异常区,KT1、KT2分析为隐伏地质构造影响。查明了21209工作面探测范围内煤、岩层的富水情况,达到预期目的。
In order to ensure the safe mining of the 21209 working face of Dongpan Mine and provide a reference for the formulation of water prevention and control technical measures,first of all,it was necessary to find out the water richness of the rock formations within the working floor and surrounding areas and the hidden water-conducting structures in the working face.Transient electromagnetic technology,Wenner's three-level electrical sounding technology,radio wave tunnel perspective and audio electrical perspective comprehensive geophysical exploration methods were adopted,for the hidden conductance and water-containing structures inside the working face,especially the hidden water-conducting sinking columns,faults and dense development zones probing.The results showed that there were three relatively low-resistance anomalies in the detection range,of which the S1 and S2 anomalies were rock-cutting and water-bearing reactions near the wild limestone,and the YP1 anomaly was a local water-rich reaction in the rock formation;two geological anomalies,KT1,KT2 analysis.It was a hidden geological structure.The water-rich condition of the coal and rock formations within the detection range of the 21209 working face was ascertained,and the expected purpose was achieved.
