Optimization of Stope Structure Parameters Based on the Mined Orebody at the Meishan Iron Mine

Based on the engineering background of Meishan iron mine with sublevel caving (SLC) method, in this work, we adopted method for identifying shape mined orebody (the original location blasted slice), which analyzed and determined reasonable stope structure parameters. In field test, markers were arranged slice, was measured by situ tests, reliable data achieved. The obtained through test when width drift 6 m. orebody’s compared isolated extraction zone (IEZ), difference increased increasing height. When structural parameters orebody, larger height was, smaller error using ellipsoid arrangement theory to determine Finally, optimized. 22 m, spacing 20
