Figure 1 shows the model of working face calculating stratum subsidence.
The mechanical parameters of each overlying stratum could be found in table 1.
Table 1 Geologic column and parameters of overlying strata Layers Height[m] Elastic modulus [Gpa] Density [kg·m-3] Poisson ratio J 440 15 3354 0.38 I2 455 3 2578 0.22 I1 459 5 2545 0.26 H 463 2.5 2278 0.25 G 466 4.5 2986 0.38 F 472 3 2645 0.34 E2 479 2.5 2502 0.26 E1 484 2.2 2252 0.23 D 486 1.2 1812 0.15 The subsidence of layers from D to J when the length of face advances is 140 meters is depicted in Fig.3 (Eq. (1) and Eq. (2)).
The following figures are the descriptions of porosities along the trend in 479 meters depth while face advances are 60m, 75m, 90m, 115m and 140m(Eq.(4)).
Conclusions (1)There are different movements in overlying strata.

The effect of ageing processes on the toughness and the yield strength of the Li-containing Al-Zn-Mg-Cu alloys (Al-5.6%Zn-1.9%Mg-1.6%Cu-1.1%Li-0.24Cr) was investigated.
Tensile tests were performed at a rate of 1×10 -3 m·s-1.

Fig. 1.
In the early stage, the crystallization was ruled by nucleation, therefore U=0 and the activation energy EC(x=0) = En≃479 kJmol-1.
Conclusion 1.
The values of En and Eg is 479 kJmol-1and 309 kJmol-1, respectively.
