In view of the inevitable overexploitation in the following certain years,we propose the ordered exploitation to solve the problem.

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.

Introduced composition and function of computer model of open pit mining procedure optimization design,aimed at south open pit production practical situation and geographyic condtion,carried out opimzation of mining procedure.

oreloss and dilution ratio adoptable in the aspects of controlled blasting incontact zone of rock and ore, mining procedure,loading technique, etc areproposed based on a number of commercial--scale trails.

By dynamic programming method, authors put forward a decisive method of mining procedure of large surface mining deposits.

Optimization method of open-pit mining sequence and its applications;
