    • Abstract
  • Copper ores of Daboshan mining area are stoped from remnant ore mainly, and the working condition is unsafety.For stoping safely, the Minkle elastic grade beam principle is adopted to analysis the mechanics of the roof, the broadly-defined sink speed is regarded as parameter of observing, and according to its jump characteristic to forecast roof board rupture in advance and stope ground pressing, corresponding ground pressing control measure is taken to offer the security for stoping of remnant Ores.
