查询词典 mining

The essence is how to use the mine microseism, under the unchanged mining intensity, which occurs upon accumulation of the respective low stresses, to predict the next extremum mine microseism due to occur during the stress mining environment classified by the increased isostress gradient instead of a period divided by the human experience.

Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.
