Sand and gravel reserves calculation method

Understanding sieve analysis of sand

 · Dust. This is a fine material usually below 2μm formed during the process of conversion of rock or gravel into coarse aggregates (80mm - 5mm) and fine aggregates/sand (4.75mm - 63μm). 1.3 Main principles For fine aggregates free from silt, clay and other materials which cause agglomeration, Dry sieve analysis method may be performed.

Mineral Appraisals: What is the Value of a Quarry or Mine?

The average specific gravity of sand and gravel is difficult to quantify, owing to variations in the degree of packing and water content. A factor of 111 lb. /cu. ft. is commonly used for sand and gravel, equal to about 3,000 lb. or 1.5 tons/cu. yd.

values of the cumulative weight, and the weight of the gravel fraction alone, represents the weight of the sand fraction. Any remaining sediment in the bottom pan (<63µm) is added to the corresponding graduated cylinder. The silt/clay fraction is determined by filling the corresponding graduated cylinder to 1,000 mL with deionized water.

Sand control techniques

 · Several techniques are available for minimizing sand production from wells. The choices range from simple changes in operating practices to expensive completions, such as sand consolidation or gravel packing. The sand control method selected depends on site-specific conditions, operating practices and economic considerations.

Sieve analysis of aggregates

In this method, the soil is sieved through a set of sieves. Sieves are generally made up of spun brass and stainless steel. As mentioned above, the sieve analysis is done for coarse-grained soils. The coarse-grained soils can further be divided into gravel (size > 4.75 mm) and sand (size from 75µ – 4.75 mm), where µ represents micron.
