open cast coal mining blasting pattern

Carsten Drebenstedt

By combining the terms of open cast blasting design pattern, production planning, noise, vibration, fly rock, and estimation of drilling and blasting costs, as a decision making tool for planning surface coal blasting efficiency, reducing the environmental impacts of noise, vibrations, and fly rock from the surface coal blasting can be created.
