| Abstract: | The paper carried on experiment for the large
dimension coal sample from XinzouYao No.8914 fully mechanized sublevel caving face by
using MSS 300 model real three axes pressure machine,and studied the regularities of coal
mass cracks evolution by using fractal theroty.It will provide necessary theoretical basics to
study the cracks evolution regularities of top coal in sublevel caving face and to adopt artificial
weakening for top coal.It also probed into the new method for selecting the reasonable
mechanics parameters on numerical simulation of sublevel caving face. |
