Controlling the Adverse Effects of Blasting This module addresses the control of offsite impacts that result from blasting, namely: • vibrations, • airblast, and • flyrock. Much of the information in the module is derived from the Surface Mining Control and Reclamation Act of 1977 (SMCRA). The performance standards apply to all

In many instances of poor blasting even this increase in stemming will not ensure complete retention, but will give the material additional time to hold. Controlled variables Toe and elevated floor problems have plagued mines and quarries for decades, but are not always a result of geology or variables that are beyond control.
