An intelligent integration system for shell nosing design was in-house developed to reduce the cost of the shell nosing design which used to depend on the designer's experience.

In this paper,the backward simulation was summarizd at home and abroad,the characteristics of shell nosing were introduced,the theory and scheme of backward simul ation of shell nosing was constructed,the determined methods of the boundary conditions were put forward in backward simulation for the processes of shell nosing.

The growth mechanism,formationcause and recovery technology of the dross in galvanizing production was discussed in this paper.

According to the particularity of the tailing-in work on 10508 coal-planer working face in Malan Coal Mine,this paper determines the tailing-in technique on the working face,and advances some improving suggestions according to the problems occurring in the course of tailing-in work.

The improvement and optimization of coarse slime recovery process in coal preparation plant;

Study on the recovery process of high-strength recycled aggregate and performance of recycled concrete

The recycling process planning of waste products is discussed systematically and the recycling process model of waste products is established.

An agent-based decision-making model of recycling process is built, the algorithm of one step recycling process supported by expert system is raised, the case based reasoning search is applied in the routing recycling process network, and the system implementation process and method are analyzed.
