Controlling the Adverse Effects of Blasting

   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

Quarrying Of Stones Methods Site Selection Preparation

   Quarrying by blasting involves a series of systematic operations such as drilling of blast-holes charging of blast-holes and firing the shots. (1) Drilling of blast-holes A blast-hole is a hole of suitable diameter and depth driven at a properly selected location on a rock for being charged with an explosive.

(PDF) ROCK BLASTING AND AGGREGATE PRODUCTION

Introduction Blasting operations are performed to break rock for the purpose of quarrying for processing in an aggregate production operation or to excavate a right-of-way 1 . Blasting is accomplished by discharging an explosive that has either been placed in an unconfined manner such as mud capping boulders or is confined as in borehole 2 .

Construction Blasting Risk Management Expert

Construction Blasting Risk Management. As we can see from the November 2008 article " Construction Blasting Fundamentals " there are many forms of risk associated with blasting work. It is clear that despite these risks experience reveals that blasting can be performed without incident when adequate risk-control measures are used to manage

Quarry industry worker competenceOperational Guidance
