Mechanical Model and Analysis on Movement of Rock Strata between Coal Seams in Pillar Upward Mining of Left-Over Coal GuoRui Feng a, Jing Zheng *,b , YaFeng Ren c, CongMing Zhong d and LiXun Kang e 1College of Mining Engineering, Taiyuan University of Technology, Taiyuan 030024, China azjgenq@yahoo.cn, bfguorui@163.com, crenyafeng0322@163.com, ddahuamm2002@yahoo.com.cn, ekanglixun@sohu.com *Corresponding author Key words: pillar, upward mining of left-over coal, rock strata between coal seams, movement Abstract Work out control measures for pillar upward mining of left-over coal, in view of coal floor movement, this paper analyzes theoretical foundation and mechanical properties of mechanical model on coal floor movement of rock strata between coal seams in pillar upward mining of left-over coal and presents a simplified corresponding mechanical condition.
Taking into the relation between layer movement and time consideration, the PTh model is used to show its rheological properties.
It shows that overlying rock movement above the goaf is a temporal and spatial process, which has the obvious rheological properties and the rock movement is relevant with time factors significantly.
If time properties are not considered, according to the basic hypothesis of elastic-plastic mechanics, the rheology instantaneously finished, thus many instantaneous deformations can't be explained.
The PTh model is used to show rheological properties about coal floor movement, by using a two-dimension model, mechanical model of coal floor movement is set up and both ends of cantilever beam are fixed.

Mechanical Properties of Filler Metal in Si3N4/Austenitic Stainless Steel/Si3N4 Joints as Measured by Nanoindentation and Its Relationship to the Interfacial Strength Daniel Cáceres1, Raquel Polanco2, Pilar Miranzo2 and María Isabel Osendi2 1 Dpto.
Recently, some efforts have been devoted to relate nanoindentation derived properties -elastic modulus and hardness- to other mechanical properties of metals such as tensile strength or to the same properties measured by bulk methods [1-2].
Furthermore, due to the tip size and positioning capability, the nanoindentation technique allows evaluating elastic properties as a function of the distance to the bonding interface, which at times can be of interest [3].
The increase in E and H could be attributed to two factors, such as the nucleation of nitride species (CrxNy) within the interlayer after bonding [7] or even to the joining process itself as the foil is subjected to temperature and pressure affecting dislocations.
Summary The shear strength of Si3N4 joined using different ss foils was dependent on the composition of minor elements and was directly related to the elastic properties of the foils after bonding.

Tool materials are often hard to choose correctly because they are affected by many factors besides parameters of cutter geometry and cutting, such as property of tool material and machinability of workpiece[1].
Matching of dynam property of tool and work materials Matching of mechanical property of cutting tool and workpiece material signifies the adaptation of property parameters for strength, toughness and hardness to satisfy the technical requirements of HSM.
Tools of different physical properties have diverse machinability for different materials.
As high cutting temperature of HSM seriously affects the property of cutting tool, therefore, in most case, the invalidation of tool depends on thermal property of tool material.
