The test study on impact of pre-setting ore pillar on schistosity rock stope stability

Schistosity rock is special rock mass structures, its main failure form is structural failure. Upward rock for easy rib fall with the mining height for schistosity rock stope, thus cause secondary dilution and affect safety mining.Through numerical simulation test and similar simulation test, pre-setting ore pillar in schistosity rock stope, the results of the research increased mining height and ensured safety mining.
