Jun 05, 2012· volume of a cone: 1/3 *Pi*the radius squared *the height Unless the cone is uniform its useless. If the aggregate is the all same size or you have piles of the same size aggregate you can simply make a small trapezoid. I hope yout loader operator is leaving the loader on the ground and not crawling up the pile which will cause a tip over.

Estimate the volume of an excavated pile of material in cubic yards. If you look at the second image, the footprint, length A is not the overall length. If you subtract that from the total length and add both ends, you end up with a cone that has a diameter that is equal to length B. The calculation is done in two parts.

Compaction by soil piles. This method has been applied in Russia since 1934. Currently, percussion drilling machines are used with heavy rods. The percussion drill of diameter of 50–60 cm has typically coneshaped ends at a 30°. Boreholes up to 15 m long are dug around where a compacted zone is to be produced with a diameter of up to m.

Mining Mining Surface mining: It has been estimated that more than twothirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
