摘要: 淮南矿区老区大倾角煤层工作面较多,其A 组煤层开采过程中受到底板灰岩水的威胁,需提前进行探测与处理,但大倾角条件下直流电穿透方法适用性需要得到确认。论文结合大倾角A 组煤层工作面开采地质条件,进行物理模型构建及测试实验,并通过现场探查实践,对双巷并行电透视成像方法进行研究,获得了三维电透视数据采集、处理与反演关键技术认识。认为通过三维全空间电穿透数据采集及处理,对底板岩层富水特征探查分辨具有良好的效果,可为大倾角煤层工作面防治水技术措施制定提供依据。

Abstract: In the old mining area of Huainan coalmine a mass of the working faces with high dip angle often poses a threat of water disaster from limestone stratum of the working face floor during the exploitation process of coal seam group A. The detection and disposing measure must be done ahead of mining schedule. But the method applicability of penetration by direct electrical method for the coal seam with high dip angle needs to be confirmed. In the article the physical model has been conducted according to the mining geological conditions of coal seam group A with high dip angle, and test experiment has been finished. Through exploration practice, the imaging method of parallel penetrating with direct electrical method between double laneway of working face is studied, and the cognition for the key technology of data collecting, process and inversion about 3D penetrating of electrical method have been gained. Through the data collection and process of 3D whole space, the penetrating method with direct electrical method can get good resolution effect for the containing water characteristic of the floor rock stratum. It can provide the basis for formulating the technical measures of water control for the working face with high dip angle.
