Snowy 2.0 Pumped Storage Power Station
Snowy 2.0 Pumped Storage Power Station or Snowy Hydro 2.0 or simply Snowy 2.0 is a pumped-hydro battery megaproject in New South Wales, Australia. The dispatchable generation project expands upon the original Snowy Mountains Scheme (ex post facto Snowy 1.0) connecting two existing dams through a underground tunnel and a new, underground pumped-hydro power station. It is expected to supply 2.2 gigawatts of capacity and about 350,000 megawatt-hours of large-scale storage to the national electricity market. It is the largest renewable energy project under construction in Australia. It includes one of the largest and deepest cavern excavations ever undertaken. It also includes the longest tunnels (at 27 kilometres in length) of any pumped-hydro station ever built. It is designed for grid stabilization, to be a backup at times of peak demand, and for when solar and wind energy are not providing sufficient power. It provides valuable firming capability. Snowy Hydro acts like a giant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowy Mountains
The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion in southern New South Wales, Australia, and is the tallest mountain range in mainland Australia, being part of the continent's Great Dividing Range, a cordillera system. It makes up the northeastern half of the Australian Alps (the other half being the Victorian Alps) and contains Australia's five tallest peaks, all of which are above , including the tallest Mount Kosciuszko, which reaches to a height of above sea level. The offshore Tasmanian highlands makes up the only other major alpine region present in the whole of Australia. The Snowy Mountains experience large natural snowfalls for several months of the year; with significant accumulation during May, June, July, August, September and October with the snow cover usually melting by November (although it can occasionally persist through high summer and the next autumn). It is considered to be one of the centres of the Australian ski industry d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feasibility Study
A feasibility study is an assessment of the practicality of a project or system. A feasibility study aims to objectively and rationally uncover the strengths and weaknesses of an existing business or proposed venture, opportunities and threats present in the natural environment, the resources required to carry through, and ultimately the prospects for success.Justis, R. T. & Kreigsmann, B. (1979). The feasibility study as a tool for venture analysis. ''Business Journal of Small Business Management'' 17 (1) 35-42. In its simplest terms, the two criteria to judge feasibility are cost required and value to be attained. A well-designed feasibility study should provide a historical background of the business or project, a description of the product or service, accounting statements, details of the operations and management Management (or managing) is the administration of organizations, whether businesses, nonprofit organizations, or a Government agency, government bodies throu ...

Drilling And Blasting
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite. Before the advent of tunnel boring machines (TBMs), drilling and b ...

Water Jet Cutter
A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using an extremely high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber. Waterjet cutting is often used during the fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods; examples of such materials include plastic and aluminium. Waterjet cutting is used in various industries, including mining and aerospace, for cutting, shaping, and reamer, reaming. History Waterjet While using high-pressure water for erosion dates bac ...

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. ''Sink'', and ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by Karst topography, karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of Metre, meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Florence Violet McKenzie
Florence Violet McKenzie (; 28 September 1890 – 23 May 1982), affectionately known as "Mrs Mac", was Australia's first female electrical engineer, founder of the Women's Emergency Signalling Corps (WESC) and lifelong promoter for technical education for women. She campaigned successfully to have some of her female trainees accepted into the all-male Navy, thereby originating the Women's Royal Australian Naval Service (WRANS). Some 12,000 servicemen passed through her signal instruction school in Sydney, acquiring skill in Morse code and visual signalling (flag semaphore and International Code of Signals). She set up her own electrical contracting business in 1918, and apprenticed herself to it, in order to meet the requirements of the Diploma in Electrical Engineering at Sydney Technical College. Described at the time as Australia's "Mademoiselle Edison", in 1922 she became the first Australian woman to take out an amateur radio operator's licence. Through the 1920s and ...

Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. TBMs are an alternative to drilling and blasting methods and "hand mining", allowing more rapid excavation through hard rock, wet or dry soil, or sand (although each requires specialized TBM technologies). TBM-bored tunnel cross-sections extend up to (through June 2023). TBM tunnels are typically circular in cross-section, but may also be square or rectangular, or U- or horseshoe-shaped. Much narrower tunnels are typically bored using trenchless construction methods or horizontal directional drilling rather than by TBMs. TBMs limit disturbance to the surrounding ground and produce a smooth tunnel wall, which reduces the cost of lining the tunnel; it also allows for tunneling in urban areas. Large TBMs are expensive and challenging to construct and transport, fixed costs which become less significant for longer tunnels. Tunneling speeds generally decline as tunnel size in ...
