Abstract:

Coordinated open-pit with underground mining order is related to the degree of its restrict and influence between two different mining system. Under the background of coordinated open-pit with underground mining engineering practice in PingShuo mining area. The characteristics of slope deformation destruction of open-pit coal mine in different coordinated open-pit with underground mining order was analysed by numerical simulation. According to the results of the analysis, the mining model of open-pit mining lagging behind underground mining was suggested in coordinated open-pit with underground mining practice based on the point of keep slope level and stability, and open-pit mining progress should lagging behind underground mining active period.

Key words: coordinated open-pit with underground mining, mining order, slope deformation destruction, underground mining disturbance
