Analysis of Apparent Resistivity Response on Water and Gas in Low Resistivity Zone by Underground DC Advance Method
摘要
Abstract
The apparent resistivity is sensitive to water response.In order to detect the gas content in the roadway by using the direct current method,we need to synthetically analyze the gas content and groundwater in the coal seam.The test area is located in 12205 working face of Zhaojiazhai Coal Mine.There are 6 low-resistance anomaly areas in the working face,and 4 of them have good water-borne properties and low gas content.In the other two,the gas content of the low resistance abnormal zone is high and the water rich is poor.The low resistivity abnormal zone of mine reflects the characteristics of coal seam water or gas.But,when the groundwater is small,the gas content is small,and when the groundwater is small,the gas content is big,so,the relationship between the two is consistent with the normal gas occurrence of coal seam.关键词
