摘要：Focus on a -400m level stoping in a gold mine, the ANSYS numerical software was used to study the stope structural parameters in upward drift cut-and backfilling mining methods. First, according to engineering experience, the design of stope structural parameters was obtained. Then the stoping process of both the first drift and the second drift was simulated by the numerical software. The vertical maximum displacement and the vertical maximum stress were selected as evaluation indexes for analysis. The result shows that the third project, whose drift width is 4 m and layer height is 3 m, have the best effect with the less displacement and stress compared with other projects. © (2014) Trans Tech Publications, Switzerland.
