大倾角煤层工作面底板岩层富水异常区探查方法研究
Study on detection method of anomaly watery area for the floor rock stratum of the working face with high dip angle
摘要
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 ex-ploitation 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 ex-periment 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.关键词
