【摘要】 大功率激电法在双阳煤田找煤的应用中,证实了山河推覆构造的存在;在充分研究工作区的地质、地球物理特征前提下,恰当地选用了方法技术,并正确理解异常的地质、地球物理意义,取得了较好的找煤效果,在Ⅰ号剖面的激电异常上经钻探和坑探证实磨盘山组灰岩下存在质量较好的可采煤层。更多还原

【Abstract】 In application of the large power in duced polarization for ore-search in the Shuangyang coalfield. The existence of the Shanhe nappe structure was confirmed. According to the geologic and geophysical characteristics in the study area, we chose appropriate methods and technique, and accurately understanding the geologic and geophysical significance of the anomaly, obtaining a relative ideal result for coal prospecting. On the basis of the large power induced polarization method of the section Ⅰ, through anomaly detection by using drill-hole exploration and pit prospecting methods, it is verified that the relative ideal commercial coal seam occurred in the Mopanshan Formation limestone.更多还原
