China encourages the development of circular economy of coal at present , the coal companies in China are also elongating industry chain, expanding industrial categories and creating the development mode of coal circular economy industry chain, and coal washing, coking, coal chemical industry, electricity, building materials and industrial system has been taken in shape.
Industry argument, MK is said that coal mining, XM is said the coal washing plant, GD is said gangue power plant, MD is said the coal plant, JH is said the coking plant, JC is said the building materials factory, JCH is said methanol plant.

(a) Side View (b)Vertical View Fig. 2 FEM model Table 1 Material parameters Elastic Modulus（Pa） Yield Stress（Pa） Density（kg/m3） Poisson ratio Harden Parameter Failure Strain 3.25e10 4.8e6 2500 0.25 0 0.025 Due to the bridge pier is failure in order to eliminate in the process of explosion, and do not need to consider its internal force, the existence of different times can be thought of only playing a supporting role, so the determination by elastic material without considering the plastic process, only in a fixed period of time will eliminate it.
Since this article main focus on the response of the ground when the bridge collapsing, in order to improve the computation efficiency and ensure the reliability of data, the road, clay layer adopt elastic-plastic material in model.
