Electrical Survey and Research on Spatial Distribution of Room and Pillar Goaf in Zhaojialiang Coal Mine in Northern Shaanxi Province
摘要
Abstract
The shallow buried hidden room and pillar goaf in Jurassic coalfield in northern Shaanxi province has become a key hidden danger restricting coal mine safety production due to its discrete spatial distribu-tion and complex shape.In order to achieve precise detection of goaf and study the development law of wa-ter conducting fracture zones,taking Zhaojialiang coal mine as the research area,a four-dimensional framework of"geological exploration—geophysical scanning—drilling verification—logging precision"has been constructed.By using transient electromagnetic method(TEM)and high density electrical method,combining with ground drilling and television logging technology,distribution characteristics of goaf and the mechanism of overlying rock failure have been reavealled.It is showed that comprehensive geophysical technology system can effectively reduce the ambiguity gained by using a single method.6 low resistance abnormal areas have been circled in 5-2 coal seam.The total area is approximately 363200 square meters.They are speculated to be goaf water accumulation areas.2 goaf water accumulation have been circled in 4-2 coal seam,and 3 goaf water accumulation have been circled in 3-1 coal seam respectively.In the detec-tion of water conducting fracture zones,the collaborative application of ground drilling and television log-ging technology has achieved quantitative evaluation of fracture development height and connectivity.The research results can provide theoretical basis and technical support for disaster prevention and control in the goaf of shallow buried mining areas in the western region.关键词
