Powder Factor: The Ineffective Design Tool. Since the first application of black powder for blasting in 1627, blasters and engineers have been using powder factor as a design tool. Powder factor is the ratio of pounds of explosive used in a blast to the total volume of rock blasted; a typical range for surface blasting is to pounds per ...

The Global Coal Mine Tracker uses the exclusion factor (%) for all coal types, since emissions from coking coal should still be counted in general inventories. When GCMT data is used for a general compilation, it uses, but when the compilation is relevant to power sector only, it includes for coking coal.

"Large surface coal mines in Wyoming's Powder River Basin ship millions of tons of coal per annum, moving millions of cubic yards of overburden to mine the coal. Much of this volume is blasted in the form of benches, a common mining technique. Increases in production and scale of equipment in the past thirtyfive years have created a paradigm shift for drill and blast personnel at these large ...

Powder Factor. Powder factor and the appropriate charging of drill holes is very important in underground mining as malfunctions are very common in the close proximity of loaded holes and the confining environment creating unfavorable breaking conditions. The above equations may be used to estimate parameters of a blast with other known values.

Some gunpowders, like 3N38, can make Major power factor and stay within established pressure limits. Vihtavuori's load data for the 9X21, which can be used for the 9 mm Luger, shows a maximum load with 3N38 and 115grain bullets that make Major power factor. It even makes Major from my Lone Wolf barrel in a GLOCK 19.

Powder factor is expressed in many different forms. Essentially it is a measurement of explosives per quantity of rock. The typical variation of this that we use on a daily basis is how many pounds of explosives per cubic yard of rock. This gives us a baseline of how we need to go about fragmenting rock for each particular application.
