Methods of Quarrying

 Quarrying is the process of extracting natural stones from the earth's surface. There are several methods of quarrying that are used in the stone industry, each with its advantages and disadvantages. Here are some of the most common methods of quarrying:


Digging method: This is the simplest method of quarrying and involves digging a large pit or hole in the ground to extract the stone. This method is most commonly used for softer stones like sandstone and limestone.


Drilling and blasting method: This method involves drilling a series of holes in the rock face and then inserting explosives into the holes. The explosives are then detonated, which breaks the rock into smaller pieces that can be extracted. This method is most commonly used for harder stones like granite, marble, and basalt.


Wire sawing method: This method involves using a diamond wire saw to cut through the rock. The wire is fed through a series of pulleys and powered by a motor, which allows it to cut through the stone with ease. This method is most commonly used for cutting large blocks of stone.


Chain sawing method: This method involves using a chain saw to cut through the rock. The chain saw is powered by a motor and is fitted with a diamond-tipped chain, which cuts through the stone quickly and efficiently. This method is most commonly used for cutting softer stones like sandstone and limestone.


Wedging and splitting method: This method involves using wedges and chisels to break the rock into smaller pieces. The wedges are driven into the natural cracks and fissures in the rock and then hammered until the rock splits. This method is most commonly used for softer stones like sandstone and limestone.


In conclusion, the method of quarrying used depends on several factors like the type of stone, location of the quarry, and the desired size and shape of the stone. Each method has its advantages and disadvantages, and it is essential to choose the most suitable method for the specific application.

Common Terms for PVC Pipe, Fittings, and Parts

  Common Terms for PVC Pipe, Fittings, and Parts ABS  or Acrylonitrile Butadiene Styrene is a group of plastics made from polymers with prescribed percentages of acrylonitrile. Adapter  is a fitting that joins two different pipes together. It can also join threaded with nonthreaded pipe. Aging  is the act of exposing materials to an environment for a period, or the effect on materials that have been exposed to an environment for an extended. ASTM  stands for American Society for Testing and Materials. Known today as ASTM International, this is a leader in international standards use for safety, quality and consumer confidence. There are a number of ASTM standards that apply to PVC and CPVC pipe and fittings. Beam Loading  is the process of applying specified force to a piece of pipe that’s supported at two points. This is usually expressed in pounds per distance between the centers of the supports. Belled End  pipe is made to flare out at one end, whic...

Mix Proportioning using IS code

 Mix proportioning is the process of determining the quantities of materials needed to produce concrete with the desired properties. The Indian Standard Code for mix proportioning is IS 10262:2009. Here are the steps to follow for mix proportioning using IS code: Determine the target mean strength of concrete (fck): This is the strength that is required for the concrete to perform its intended function. It is usually specified in the project specifications or can be determined based on the intended use and the requirements of the structure. Determine the water-cement ratio (w/c): The w/c ratio is the ratio of the weight of water to the weight of cement used in the concrete mix. The maximum w/c ratio specified in IS code is 0.50. Determine the cement content: The cement content is determined based on the target mean strength and the w/c ratio. The formula to calculate the cement content is: Cement content = (fck + 1.65 x standard deviation) x (1/w/c) x 1000 Where fck is the target m...
