TIME-LAPSE CHANGE PATTERN AND MECHANISM OF RESISTIVITY OF COAL SEAM FLOOR MINING DAMAGE BASED ON INTER-HOLE DC PERSPECTIVE

Time-lapse change pattern and mechanism of resistivity of coal seam floor mining damage based on inter-hole DC perspective

During the coal mining process, the change in the floor stress state of coal seam will produce deformation and failure.The seam floor failure in different coal mining processes has a certain law.At present, Jam Pot Cover the water disaster monitoring of coal seam floors based on the DC resistivity method mainly focuses on the resistivity response c
