On the day of the blast, the explosives are delivered and taken to the site of the blast. Detonator cord is placed in each hole and the holes are then loaded with high explosives to within a few metres of the top. The remaining depth is "stemmed" with quarry dust or fine aggregate. The site is cleared. Sirens are sounded to make sure that everyone nearby is warned. The detonators are connected ...

PROCEDURE FOR DETERMINING ROCK WEIGHTS, SIZES AND GRADATIONS

Tables 1 through 5 have gradation guidelines for D50s of 4 inches through 12 inches. The smaller (i.e., 1 and 2 inch) diameters shown should be considered as “weight of material” rather than “number of rock.” The tables can be used to produce gradation sample piles showing the upper and lower limits of the desired gradation. These piles can be used in the rock quarry to provide the ...

19/03/2020  The equipment required for stripping, blasting, crushing, and screening is very expensive. However, today’s equipment can consistently produce aggregate material that is in within specifications. Stockpiling may seem to be a trivial part of aggregate production but, if it is done incorrectly, it can cause a perfectly “in spec” product to become out of spec. This means some of the cost of ...

BF Sisk Basalt Hill Quarry Exploration and Test Plan –

The controlled blast was used to fracture in situ rock and obtain the type and size of rock material needed. During the explosions material was fractured and lifted upwards and partially away from the quarry face in response to the timing sequence of explosives. In each of the blasts approximately 20,000 lbs. of explosives were placed in 25 to 30 holes drilled across 200 yards of quarry ...
