On the Bifurcation of the Remaining life under Multi-level Fatigue;

After a theoretical analysis of the critical fork of the system,the analyzing model of discipline cluster evolution,competition and symbiosis relation between each discipline in discipline cluster evolution has been discussed.

A numerical method is used to simulate the forking process of a new chaotic system which is simple in topology structure but complicated in dynamics behavior.

When Gaohe exploration area of Qinshui coalfield was undre construction, 15# coalseam appearing branch was discovered on eighteenth exploratin line from middle part to north, in order to make full use to coal resource,branch of 15# coal seam was analyzed with driling material from deposit environment theroy,it has guiding meaning to arrangement and mining in future.
