A Study of Millisecond Blasting on High Bench at Barun Iron Ore Operation

A Study of Millisecond Blasting on High Bench at Barun Iron Ore Operation

To improve the productivity and efficient of modern large-scale open-cut mines, a number of technologies are developed and trialed, including new blasting equipment, larger blasting holes, high benches, air spacing, and short-delay blasting within holes. However, the relative blasting parameters nee...
