Mining Ecological Safety Problems Mineral resources are the important material base of human society development.
The rapid development and utilization of mineral resources has provided the important material guarantee for social economy fast and steady development.
In addition, the reputation of "the home of non-ferrous metals" also only means the supply of raw materials, and don’t combined non-ferrous metal advantages with metallurgy, materials of industry development.

Theoretical Basis of Structural Fracture Analysis Fracture Model and the Stress Intensity Factor (SIF).For the fracture cracks in isotropic homogeneous materials, it is usually divided into three types based on its displacement mode: (Opening model), (Sliding model), (Tearing model).Opening model is defined as, crack will be expanded under the tensile stress which perpendicular to the crack surface.
