Abstract


Coalfield water conductivity structure is one of the main factors that caused the coalfield water damage , its exploration and evaluation is an important issue in the coalfield hydrogeological study also coalfield construction and mine safety work are important issues that must be addressed . Transient electromagnetic exploration technology in recent years is widely used in hydrology and engineering exploration , which has many other geophysical methods can not match the advantages, such as close - up observations, the volume effect is small , directional , high resolution , low sensitive resistance , rapid construction , is being increasingly used in coal water harm constructed exploration. This article looks at the ways and means for practical work , discussion and research coalfield water conductivity structure exploration outside the industry and within the industry, some of the specific aspects of the work . Focus on discussion and research on the processing chain in apparent resistivity correction and remove the impact of the one-dimensional inversion work , and then to strike a more reasonable apparent resistivity processing results provide a reference and guide to determine and identify the hydraulic conductivity structure . And the actual work area , interpretation and analysis of the coalfield water conductivity structure , water-rich area , the collapse column as well as the entire coal-bearing strata water conductivity structure characteristics and summarize research for the exploration of the coalfield water conductivity structure ideas and work program.
