The Prospecting Technology for Water Enrichment of Water-inrush Geological Structure in Mine
YANG Wu-yang
Abstract：Karst collapse column, fracture, gob area are the main geologic structures that causing the mining water inrush.Through the comparing research on the application of every kinds of geophysical prospecting , the 3D seismic exploration is adopted to find out the type , size, and distribution of water inrush geological struc-ture, and the transient electromagnetic method and SYT electromagnetic sounding method is used to prospect the watery feature of water inrush structure.The research suggests that the formation water abundance is rela-tive to the size of the apparent resistivity , the watery layer has low apparent resistivity while the low and non -watery layer have high apparent resistivity.The water enrichment of geological structure was analyzed accord-ing to horizontal and longitudinal apparent resistivity contour map.This study will provide geological basis for danger evaluation of water inrush.The prospecting results in Huainan mining area suggest that there are two collapse columns in the detection region , the northwest collapse column is free from water and the east one is high with water.The actual laneway shows the data is coincide with the prospecting results , which provides a efficient integrated geophysical method for prospecting the water enrichment of geological structure .
