Optimization of Structural Parameters of Strong Mining Stope in the-360 m Middle Section of Daye Iron Mine
The development and mining stage of the-360 m middle section of Daye Iron Mine is lag-ging behind,and the production capacity is insufficient.In order to determine the relatively safe and eco-nomic structural parameters of a strong mining stope,FLAC3D numerical simulation is used to analyze the dis-placement and plastic zone distribution characteristics of the roof and backfill in the stope with different structural parameters during the stope stope and filling process,and compare the mining quantity and stope production capacity of different stope structural parameter schemes.The reasonable structural parameters of high intensity mining stope in the east and west are determined.The research results show that after increas-ing the structural parameters,the quantity of stope cutting works is reduced by 28.5%,and the comprehen-sive production capacity is increased by 24.2%,which is helpful to shorten the stope preparation period un-der the current state of mining imbalance,and ensure the productivity balance in the process of continuous mining.
