Verification Methods and Exploration of Geophysical Anomaly Zones
Mine water damage is one of the main hazards affecting coal mine safety production.In order to strengthen the ability of coal mine water prevention and ensure the safe mining of coal mines,based on the implementation standards of"geophysical exploration first and drilling verification"for coal mine water prevention and control,this paper took Zhengzhu Coal Mine as the research object,and used transient electromagnetic method to explore the abnormal geophysical area 15J-1,providing a target area for drilling,reducing the amount of drilling work,improving drilling accuracy,and eliminating safety hazards.By using various means to verify the abnormal area,it is determined that the 15J-1 geophysical anomaly area is the actual coal seam area of the 15#coal seam,with an average coal thickness of 5.2 m.The geological conditions are simple,and the overall structure is monoclinic,without mining damage areas and water hazards.
