The finite element model for interface crack of bi-material is set up, the friction phenomena of interface between two materials is simulated.
Due to the interface crack is easily produced in joint with different properties of two materials, so the bi-material-interfacial cracks are the one of the key research of fracture theory.
The finite element model for interface crack of bi-material is set up, the friction phenomena of interface between two materials is simulated[5].

Introduction Today, one of the main tasks in the field of the development of silicate materials is the creation of effective heat-insulating building materials and the reduction of their cost.
The use of local regional natural raw materials in the development of technologies for producing silicate materials will reduce the cost of the final product and increase the raw material base for the production of silicates [1-6].

Preparation System Design of Filling Material with Coal Gangue as Coarse Aggregate Youxia Sun1, a, Dawei Ren2,b 1Key Laboratory of Mining Disaster Prevention and Control of Education Ministry, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China 2College of Natural Resources and Environmental Engineering, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China asyxljl@sohu.com, bdawei_ren_2000@163.com Keywords: coal gangue, green mining, preparation system, filling material Abstract.
Thus far there are mainly four kinds of filling materials, which are high water materials, solid materials, paste filling materials and paste-like filling materials.
However, the preparation systems of the three filling materials are located on the ground, which must cause the secondary pollution by coal gangue processing and increase the transport cost by lifting the coal gangue out of the shaft and carrying the filling materials to underground.
The performances of the two materials developed meet the requirements of gob-side entry retaining and backfilling.

But in many gob grouting fill projects, due to the lack of fly ash, we need to look for other low-cost grouting materials.
Study was made through laboratory experiment on the properties of cement-coal gangue materials used for the gob grouting.
