Abstract

 

Blasting operations cause several adverse environmental effects and may result in safety problems. With the development of new explosives systems and initiation devices, blast design and execution techniques, the blasting process has now become more efficient and safer than before. Use of software tools for blast design, support in execution, blast monitoring and analysis makes it possible that damages and dangers from blasting can be predicted before blasting. These adverse impacts of blasting can be controlled and reduced. Several software are available for prediction of vibrations, airblast, wave front reinforcement, flyrock, dust plume movement resulting from blasting. Prediction tools can be used before carrying out blasts to control environmental impacts and follow safety norms. This paper also gives examples of predicted parameters and changes which can be made before blasting to control adverse impacts.

1. Abstract 

Blasting is one operation which impinges on efficiency of entire operation and results in poor image due to environmental impacts. Adverse environmental effects of blasting ranging from ground vibration, air blast overpressure, dust, fumes, fines and the potential for fly rock may make entire operation as harmful to environment and society. It is important to control all these effects while carrying out blasting operations as increasingly projects are being subjected to scrutiny and at times closure. Conventional blasting practices and techniques in mining and infrastructure construction industry are unable to improve efficiency and mitigate environmental hazards. Poor blasting design and execution not only has negative economic consequences, but is also a safety and environmental hazard. Efficient blasting with reduced environmental effects requires suitable planning, good blast design, accurate drilling, the correct choice of explosives and initiation system, blast execution, adequate supervision and considerable attention to details. With the development of new explosives systems and initiation devices, blast design and execution software tools, the blasting process has now become more efficient and safer. Blasting operations are utilizing technology systems that underpin rock blasting in open pit and underground mine operations, such as predictive modelling, blast design, radio-controlled detonation, real-time monitoring of drilling, charging and post-blast data analysis. Across the blast lifecycle, Information Technology (IT) systems are being used to record, manage and analyse data being generated.
