Dragline excavator:- A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. Most crawler cranes, with an added winch drum on the front, can act as a dragline. These units (like other cranes) are designed to be dismantled and transported over the road on flatbed trailers. Draglines used in civil engineering are almost always of this smaller, crane type. These are used for road, port construction, pond and canal dredging, and as pile driving rigs. These types are built by crane manufacturers such as Link-Belt and Hyster. The much larger type which is built on site is commonly used in strip-mining operations to remove overburden above coal and more recently for oil sands mining. The largest heavy draglines are among the largest mobile land machines ever built. The smallest and most common of th...

WHAT IS MINING:- WHAT IS MINING:-   Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining operations u...

Himalayan Mountain Range:- The chain of Himalayan Mountain Range The chain of Himalayan mountain ranges stretches on the northern borders of India in an east-west direction. These mountain ranges run for about 2,400 kilometers from the Indus River in the west of the Brahmaputra River in the east. The average width of the Himalayas is 160 to 400 km. In fact, the Himalayan Mountain is not just one range but a group of three mountain ranges running almost parallel to one another all along its longitudinal axis. A brief description of these mountain ranges is given below:  1. Tethys Himalaya Range The Tethys Himalayan Range lies on the extreme north also known as Tibetan Himalaya merges with the Tibetan plateau. The first diastrophic movement of about 7 crore years ago gives birth to both Tethys Himalaya and Himadri. The average height is 5500 to 6000 meter and the highest peak is Leo Pergel (7420 m). 2. The Greater Himalayan Range The Greater Himalay...
