Application on Advanced Exploration of AirColumn Drilling Rig in Fast Excavation Face
In order to solve the problem of delayed advance exploration restricting production in 632 return air semi-coal rock roadway in Huangling No.1 Coal Mine,two construction schemes of advance ex-ploration operation of air column drilling machine with fast excavation face are put forward by combining field investigation,theoretical analysis and scheme comparison.The research results show that the CMS1-4000/55 drilling rig is affected by the space of intelligent fast digging equipment,resulting in insufficient al-lowable space distance,and the drilling rig can not move to the working face area for advance exploration,thus restricting production.The ZQJC-850/10.7S air column drilling rig is not affected by the space,and can carry out advance exploration at any time to ensure that the advance range meets the requirements of drilling.The application effect of air column drilling rig in advance exploration has been well verified in 632 fast excavation face,and the research results provide a basis for the formulation of water exploration and re-lease measures in similar mines,and have certain guiding significance for the prevention and control of rap-id excavation disaster.
