Industry Notebook: Quarry Operations . What is a Quarry? A quarry is an open-pit mining process designed specifically for the removal of large deposits of rock. Quarries can be found all over the world and most are located where a particular type of rock - such as granite, marble, limestone, slate, or gypsum - occurs near the earth's surface.
Similarly, quarrying operations involve a lot of breaking of different types of rocks all of which are not useful for building construction. Such waste rock or refuse has to be dumped on one or other side of the quarry, so that main quarry face is not blocked. The required dumping space should be easily available near the quarry.
QUARRY OPERATIONS Quarrying involves not only extraction of material (rock) but also crushing and screening that makes the rock suitable for use as construction material. Quarry Terminology Figure 5-10 shows the names of various quarry features. Overburden is the waste material that often overlies pit or quarry sites.
This document is intended as a guide specifically for quarry operations; however, quarry operators can seek variances, exceptions, or revisions based on site-specific facts. Quarries in the Edwards Aquifer include operations that produce dimension stone, aggregate, and sand and gravel. These quarries also come in a wide range of sizes.
The two quarries are among the very few sites of this material which successfully produce blocks in different sizes of this popular color on a regular basis. Like TAB’s stone-processing plants, even the quarries are well mechanized and use the most advanced methods of quarrying responsibly.
Quarrying of stones is an art of extracting stones from the rock beds. The place from which the stones are obtained (by digging or blasting) is known as ‘Quarry’. Quarrying differs from mining in which various operations are carried out for exploring minerals, such as coal, quartzite, etc. from a mine under the ground.
