4. Extraction: Extraction is the process of obtaining natural stones from the earth’s surface using various tools and techniques.
5. Blasting: Blasting is the process of using explosives to break large rocks into smaller pieces for easy extraction. It is a controlled explosion that needs to be carefully planned and executed.
6. Primary blocks: Primary blocks are large, intact blocks of stones that are extracted from the quarry. They are then further processed to produce different sizes and shapes.
7. Dressing: Dressing refers to the shaping and smoothing of stones into different sizes and shapes, such as blocks, slabs, and tiles.
8. Splitting: Splitting is the process of breaking the large blocks into smaller pieces using various techniques such as wedging, sawing, or blasting.
9. Rough blocks: Rough blocks are the stones that have been split or sawn from the primary blocks. They are then processed further to produce finished products.
10. Waste: Waste refers to the unusable stones or fragments left behind during the extraction and dressing processes.
11. Quarry face: The quarry face is the exposed vertical cliff or wall of the quarry where the extraction of stones takes place.
12. Bench: A bench is a horizontal step in the quarry face created by removing layers of overburden and stones.
13. Ramp: A ramp is a sloping road or track created to facilitate the movement of heavy machinery and equipment in and out of the quarry site.
14. Quarry haul road: It is a specially designed road that connects the quarry face to the processing plant for the transport of extracted stones.
15. Quarry pit: A quarry pit is the area where the extraction of stones takes place. It is usually an open-pit mine, but in some cases, it can also be an underground mine.
16. Rock face: A rock face is the surface of a rock or stone exposed after the overburden is removed.
17. Face clearance: Face clearance is the distance between the working face and the edge of the quarry pit.
18. Face height: Face height is the height of the working face in the quarry that is currently being extracted.
19. Face length: Face length is the distance between the two ends of the working face in the quarry.
20. Face width: Face width is the width of the working face in the quarry that is currently being extracted.
Quarrying of stones involves a series of processes and requires an in-depth understanding of various techniques and terminology. It has a significant impact on the environment, and thus, it is essential to follow proper regulations and safety measures during the entire process. As a civil engineer, it is crucial to have a thorough knowledge of these terms to conduct quarrying operations efficiently and sustainably.
Methods of Quarrying
Quarrying is the process of extracting natural stones or aggregates from the earth’s surface for various construction purposes. It is a fundamental activity in the civil engineering and construction industry, as it provides essential materials for building structures, roads, and other infrastructure. There are several methods of quarrying used in the industry, each with its own advantages and disadvantages. In this article, we will discuss the most commonly used methods of quarrying.
1. Open-pit quarrying: This method involves removing the topsoil and overburden to expose the desired stone or mineral deposit. Heavy equipment such as bulldozers, excavators, and dump trucks are used to loosen and remove the materials. It is a highly efficient method, as it allows for the extraction of large quantities of materials quickly. However, it also results in significant environmental damage and can be dangerous for workers if proper safety measures are not followed.
2. Strip mining: Similar to open-pit quarrying, strip mining involves removing the topsoil and overburden, but it is typically used for shallower deposits. The extracted materials are then transported to a separate location for processing. This method is commonly used for the extraction of coal and other minerals.
3. Quarrying by blasting: In this method, explosives are used to break apart the rock mass, making it easier to remove. This method is commonly used for hard rock formations, such as granite or basalt. The size and timing of the explosives are carefully controlled to minimize the impact and avoid damage to the desired stones.
4. Channeling: This method involves creating vertical or horizontal cuts in the rock mass using chisels or saws. It is commonly used for softer rocks, such as marble and limestone, as it allows for precise cutting of the desired blocks.
5. Wedging: This method involves the use of metal wedges and sledgehammers to break the rock into smaller pieces. It is a labor-intensive method, but it is often used for smaller quarries or to extract smaller stones from a larger rock formation.
6. Drill and blast: This method combines drilling and blasting to break the rock mass into manageable sizes for extraction. It is commonly used for hard rocks and requires skilled workers and specialized equipment.
7. Quarrying with wire saws: Wire saws are used to cut through the rock mass by continuously moving a wire with abrasive beads across the rock face. It is an efficient method, especially for cutting large blocks of stone.
Once the desired materials have been extracted, they are transported to a nearby processing plant for further refinement and sorting. The quarrying methods used can vary depending on the type of material being extracted, its location, and the desired end use. As with any construction activity, safety precautions must be followed to ensure the well-being of workers and minimize environmental impacts.
In conclusion, the methods of quarrying vary from forceful techniques such as blasting or cutting to more labor-intensive methods like wedging or channeling.
