The system is suitable for ore-drawing management of high level and large drawing area of block cavingsystem.
该系统适合于大规模、高阶段矿块崩落法放矿生产管理。
2
The stochastic medium theory of ore-drawing can properly reflect the movements of ore and rock masses for cavingsystem.
随机介质理论可以很好地反映崩落法放矿的矿岩移动规律。
3
And study the classification system application in diagnosing the caving and drawing characteristics of top-coal, choosing support and designing drawing mechanism.
