Peabody Study: Optimizing Cast Blasting Efficiency Using ANFO With Liners

Four years ago, Peabody’s North Antelope Rochelle Mine (NARM) site started experimenting withANFO and Liners in its Cast Blasting operations. The motivation to use ANFO was based on the following:1. ANFO generates more gas thereby resulting in greater heave/movement. 2. ANFO is a more consistent product because there are less components/ingredients. 3. ANFO when protected from water contamination does not produce NOx smoke.
