Safety of barricades in cemented paste-backfilled stopesXu Zhao1,Andy Fourie1,Chong-chong Qi31. School of Civil, Environmental and Mining Engineering, University of Western Australia3. School of Resources and Safety Engineering, Central South University摘 要:In underground mining, there has been an increasing use of "cemented paste" for the backfilling......
. The distribution curves of the contact loads show an approximate parabola going downwards, which indicates contact loads are more concentrated. The front non-loading area with a ratio from 1.8% to 5.4% shows an increasing trend with the increase of penetration. However, the change of rear non-loading area is not obvious. It is believed that the conclusions have guidance for the study of rock breaking......
