Sand and gravel prospecting by the earth resistivity

The four electrode earth-resistivity method is applied to the search for sand and gravel deposits in the glaciated areas of the United States. This technique differentiates between clays and granular materials enabling the prospector to outline and roughly estimate the quantities of each without test pits or bore holes. Several examples of field surveys are given.

Sand Extraction: 1. Introduction GreenFacts

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

11.19.1 Sand And Gravel Processing

Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, and bucket wheel excavators. In rare situations, light charge blasting is done to loosen the deposit. Mining by dredging involves mounting the equipment on boats or barges and removing the sand and gravel
