Mining test results of different explosive unit consumption.
| Unit consumption/kg/m3 | Row spacing (m) | Hole bottom distance (m) | Mining effect | Open wiring condition | Top board situation | Two side-wall situation | Rear blast hole situation |
| 091–095 | 16 | 20 | Overgrind of ore | Damaged severely | Lots of falling lumps and pumice | More slanting side-wall | Serious blocking of holes and dislocation | 086–091 | 16 | 20 | Small lumpiness, partly fine ore | Small damage | More pumice | Less slanting side-wall | More plugged holes, less dislocation | 082–086 | 16 | 20 | Uniform lumpiness, less fine ore | Less damage | Partial pumice and falling lumps | Less slanting side-wall | Less plugged holes and dislocation | 075–082 | 16 | 20 | Uneven lumpiness, high lump rate | Less damage | Less pumice and falling lumps | Rarely slanting side-wall | Occasionally plugged or misplaced |
