| Abstract: | In the test of the large diameter longhole mining of No.91 orebody at Tongkeng mine,the stress and the displacement of wall rock at the stope drilling chamber were monitored.An introduction to the results is made in this paper.Meanwhile,the stress state of the chamber wall rock is studied by the elastic theory and the elastic plastic theory.The stability of the chamber and the effects of support system are analyzed also. |
