瞬变电磁勘探技术在采空区空间探测中的应用
Application of transient electromagnetic exploration technology in spatial detection of goaf
摘要
Abstract
The ecological environment of the mining area in northern Shaanxi is fragile.The large-scale exploitation and utili-zation of coal resources and the discharge of coal gangue have caused a series of ecological environmental problems,such as surface subsidence,groundwater level decline,land desertification intensification and soil pollution.Based on the analysis of the existing coal gangue treatment technology and the characteristics of coal mines in northern Shaanxi,the most thorough and effective disposal method of coal gangue is underground filling,and finding out the spatial distribution law of goaf is the prerequisite for the goaf grouting filling.The underground space of Xiaobaodang Coal Mine's 112207 working face is probed by the transient electromagnetic detection technology,the electrical law of the transient electromagnetic is analyzed,the un-derground spatial distribution law is accurately depicted,and the direction of goaf grouting filling is pointed out.关键词
