中文摘要: 在因民铜矿的地表形貌特征及查明深部采空区的基础上,结合采空区地球物理探测方法,采用高密度电阻率法及EH-4对因民铜矿大劈槽矿段的隐伏采空区开展物探工作。数据解译显示,高密度电阻率法探测浅部空区成果与实际情况的匹配度高,可圈定采空区的空间形态;EH-4可探测空区的空间位置,有效深度可达1000m,但是无法进一步测出空区的形态;对两种探测成果进行相互对比分析,取长补短,有效地提高采空区探测成果准确性和可靠性,为今后在采空区探测方面研究提供了技术支撑。
Abstract:Based on the research of geomorphic characteristics and the spatial form of deep goafs in Yinmin copper deposit, the concealed goafs of Dapicao ore-section in Yinmin mining area are developed the geophysical prospecting by using high density resistivity method and EH-4 method. According to the interpreted results, the author hold that the prospecting results of shallow goafs and actual situation has favorable matching-degree, which detected by high density resistibity method. In addition, this results could delineated the spatial-forms of goafs. Besides, the author found that the EH-4 method could detected the space position of goafs, which buried the effective depth is about 1000m, but cannot be measured the morphology of concealed goafs. The accuracy and reliability are improved by comparative analysis of this two geophysical methods, which can provide technical support to the detecting work of goafs.
