A NOVEL POWDER FACTOR BASED BENCH BLAST DESIGN METHOD FOR LARGE SURFACE COAL MINES by ANDREW CLIFFORD BLAIR A DISSERTATION Presented to the Graduate Faculty of the MISSOURI UNIVERSITY OF SCIENCE AND TECHNOLOGY In Partial Fulfillment of the Requirements for the Degree DOCTOR OF PHILOSOPHY in MINING ENGINEERING 2015
Selection of Powder Factor in Large-Diameter Blast Holes by Jack Eloranta 1995 Abstract This stone documents the relationship between material handling and processing costs compared to blasting cost. The old adage, "The cheapest crushing is done in the pit", appears accurate in this case study. Comparison of the accumulated cost of: powder, selected wear materials and electricity; indicate a
Powder Factor = Tons of rock (or cubic yards) per pounds of explosive. Normal range = 4 to 7 Shallow holes = 1 to 2 External loads = .3 Tons of Rock = Powder Factor lbs of Explosives The higher the powder factor, the lighter the load. Lower powder factor means more explosives. Example: 1.5 tons = PF of 6.25lbs BURDEN-SPACING CALCULATION From Powder Factor of 1 lb./c.y. 1. Determine
Comparative Study of ANFO Versus Emulsion Use in Anisotropic Jointed Rock Mass April 2017 Conference: 25th International Mining Congress and Exhibition of Turkey (IMCET 2017)
In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of drilling and blasting parameters. Rock fragmentation depends upon two groups of variables: rock mass properties which cannot be controlled and drill-and-blast design parameters that can be controlled and optimized. The costs of downstream
