Abstract: The frequent blockage in very deep ore passes seriously affects safe and efficient operation of underground mines.Based on the blockage in the very deep ore passes,the paper takes a very deep ore pass of a gold copper mine as the research subject,analyzes the movement rules of the ore in the ore pass,and finds that there is a vertical full-face interval movement zone between free falling zone and constant speed vertical full-face movement zone.The factors leading to blockage are summarized as follows:ore storage height is not proper,ore storage time is too long and the ore pass is damaged badly and so on.Through investigation of the problems in the ore pass operation in the gold copper mine,the blockage prevention measures for very deep ore pass are put forward,including ore pass feed level monitoring technique,ore pass reinforcement technique,ore pass ore drawing automatic control technique and so on.The application effect of techniques is good.The research can be used as reference by similar mines.
