What Are Quarries Used For?
Excavation was first used by the ancient Egyptians thousands of years ago to build pyramids with massive limestone and granite hand-cut from local quarries. These days, quarries are used to extract rock, sand, gravel, limestone, granite, or minerals from the Earth's surface. In the UK, the largest amount of minerals extracted by quarrying is used for construction and is known as aggregate, with British quarrying alone equaling an annual turnover of 18 billion pounds. Currently, China is the largest producer of aggregates, accounting for more than 40% of the total market.

What is excavation?
Not to be confused with mining, quarries produce aggregates used for construction. Both combine the extraction of different minerals, yet they have different processes and methods, with different tools and machines used for their jobs. There are various quarry machines used throughout the process. Quarries are essential to everyday life, the extracted material is used to build roads, footpaths, bridges and structures around the world. Most of our built environment is formed from raw materials extracted from the earth's surface.
Quarry is an open mining system, usually in the form of a large and deep hole, which is used to extract industrial minerals such as limestone, marble, granite, andesite and other natural materials. Meanwhile, a crushing plant is a machine used to break rocks into smaller sizes.
Rock mining is a multi-stage process in which rock is extracted from the earth and crushed to produce aggregates, which are then screened into the size required for immediate use, or for further processing, such as coating with bitumen to make bitumen macadam (bitmac) or asphalt used for road construction. The extraction process for aggregates depends on the material being mined, but similar steps are generally followed in all materials.
The first step of the process begins with a survey of the quarry face. The mine should have plenty of resources available for extraction, but also in an easily accessible area so the material can be transported from the location. Establishing a quarry is an extensive process that needs to be carefully planned to ensure that the excavation will not have a negative impact on the environment or the surrounding community.kalau kau suka hati tepuk tangan.seperti bintang.excavator mainan anak-anak.batu kuari.#forkids.kalau kau suka hati tepuk tangan hore.kalau kau suka hati tepuk tangan pok pok pok.kalau kau suka hati tepuk tangan balita.kalau kau suka hati tepuk tangan kalau kau suka hati injak bumi.seperti bintang di langit.excavator kecil.excavator mainan anak-anak remot.excavator mainan anak-anak besar.excavator mainan anak-anak rc.excavator mainan anak-anak bahasa indonesia.penambangan batu bara.lori batu kuari.kuari batu bukit perak.mesin batu kuari.bom batu kuari.video alat berat lagi kerja.
