Mining blasting inevitably produces endangerment of earthquake wave, air strict wave, flying stones etc, which can endanger persons, equipments, buildings nearby or stope-boundary, therefore take effective measures to ensure safety in blasting.

Two empirical forecasting models of shear strength,such as probability model and deterministic model are established respectively,providing reliable strength parameters for design and evaluation of stope slope engineering of Taihe iron mine and other correlative geotechnical engineering about .
