【Abstract】 The paper introduced the prediction and control technology for pressure bump during the mine roadway driving of the central transportation roadway in J 2 mining block of Pingdingshan No.11 Mine.The prevention and control process is that it was first to analyze the dangerous degree of the pressure bump,second to set up the dangerous index of the pressure bump and third to made prediction with electric magnetic radial meter and cutting method.As for the dangerous section,a blasting pressure releasing technology would be applied for the prevention and control of the pressure bump.更多还原
