According to the reasonable seam mining order and mine production scale,arranging the normal face replacement and corresponding driving engineering,the reasonable relation between mining and driving can be kept.

This paper analyses the failure process of the slope under different underground mining sequence from the angle of analysis of the slope failure feature due to combining mining,and the mining order is optimized,.

The industrial indexes of the deposit, mining sequence and the gro- uping emptied stopes are analyed and discussed, and the reasonable and viable schemes are brought up, whichguarantees the rationality and the feasibility of mining in Changba-Lijiagou lead-zinc mining area.

This paper anylises the cause of the inefficient ore production in Gaoshan Ming Area of these years, points out the exsiting problom,and based on analysing, calculating, remaking mine progress plan,puts forth rational mining sequence about this deposit and adoptable productiveness of Gaoshan Mining Area.

Several mechanisms such as forced stripper, sequenced opening, delayed goring of the sliding core are applied in the design.
