The creep parameters obtained from the inversion were substituted into Eq. (10) to produce the damage curves for different height ratios, as shown in Fig. 17. Figure 17 Damage curves of coal–rock combinations with different height ratios. Full size image Figure 17 reveals that the curve ...
The slope of the fitted line is taken as the gangue material axial (volumetric) creep index (b). The values of the creep related parameters for the gangue fill are shown in Table 4. Table 4 The results of the creep related parameters for the gangue fill material are presented. Full size...

The boring diameter, the number of borings, the spacing of borings and the strength of model coal seam were selected as the parameters of the experiments. As the model rock mass, the gypsum plate was used and as the model coal seam, artificial seam composed of the mixture of water, ...
The response analysis with the mass-on-rough-plane model has been called sliding block analysis, key elements of which include:1) Determination of the model parameters so that the pertinent dynamic property of the real structurecan be represented.2) Prediction of the response of the nonlinear ...

The model parameters were calculated by using the subsidence data from field measurements. Because of continual revising of the parameters, accurate predictions were obtained. Dai [16] carried out model tests and numerical analyses on the basic behavior of ground movements in coal mining. The ...
parameters and fitting results were obtained for each upper-stress level as shown in Table2and Fig.15, by identifying the parameters of the accumulated deformation data during the whole process of cyclic dynamic loading of the 15° joint rock mass under different disturbance stress amplitudes. From...
