Blaster's Training Modules
Presents information pertaining to the classification and properties of explosive products used in surface coal mines and quarries. Initiation Systems-This module presents information pertaining to initiation systems currently in use in blasting operations at surface coal mines.
Good drilling practices included carefully monitoring drill-rig operating parameters, taking careful notes of the changes in geology during drilling, and effectively communicating to the blasting crew any unusual conditions encountered during drilling that may affect blasting results or require changes in hole-loading practices.
Regulations in the mining-explosives industry relate to the manufacture, transportation, storage, and use of explosives. Blasters are responsible for knowing all applicable laws that affect the storage, transport,and use of explosives on their job sites. The module focuses on the storage and transport of explosives from magazines to job sites. The safety aspects of explosive handling and use are presented in other blaster-training modules.
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 infomation in the module is derived from SMCRA, which outlines performance standards applied to all surface coal mines. Simlar standards applied to all surface coal mines. Similar standards have been adopted on some State and local levels and applied to non-coal blasting operations such as quarrying and construction.
