Analysis of Supporting Rock Structure during Overlying Strata Movement in Shallow Seam Stope
Advanced Materials Research, 2011Based on existing models of main roof structure, combined with results of field observations, this paper put forward model of supporting rock structure during overlying strata movement in shallow depth. Through force and sliding instability analysis of the structure, it is obtained the relationship between block sliding and block’s lumpiness i and ...

Arabian Journal of Geosciences, 2014
Dynamic movement within strata overlying coal mines and the distribution of the movement boundary are keenly investigated topics but are hampered by the difficulties of obtaining reliable monitoring data of movement within rock masses. The work presented in this paper combines physical experiments with a digital photogrammetry method to investigate ...

Applied Mechanics and Materials, 2011
We simulate the rock’s movement and defoemation process in the coal mining, and research the overlying strata movement and deformation under the conditions of shortwall and longwall mining. The conclusion of the experiment indicates: with the method of double deck mining, the rock’s damage level in caving layer is more serious, the final subsidence ...
