What are three kinds of tunnels used in subsurface mining?
they are vertical tunnels, angle tunnels, and horizontal tunnels. THE END
When was tunnels invented?
in 1873
Why do engineers test airplane models in wind tunnels?
Because they can find a lot of information about it's flight characteristics in wind tunnels.
What is tunnel?
Tunnels is defined as underground routes or passages driven through the ground without disturbing the overlying soil or rock cover.tunnels are classified into three types:1) Traffic Tunnels 2) Hydro-power tunnels and 3)Public utility Tunnels.
What is water pressure tunnel?
Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.
How did the London underground get rid of smoke when they had steam trains?
The London Underground managed smoke from steam trains by implementing ventilation systems, including large vents and shafts that directed smoke and steam out of the tunnels. Additionally, the design of deeper tunnels and stations helped minimize smoke accumulation. In some areas, they also used mechanical fans to enhance airflow and expel smoke more effectively. Ultimately, the transition to electric trains in the early 20th century eliminated the smoke issue altogether.
What types of tunnels are there?
Tunnels can be classified into several types based on their purpose and construction methods. The main categories include transportation tunnels (for vehicles, trains, or pedestrians), utility tunnels (for water, sewage, electricity, or telecommunications), and mining tunnels (for resource extraction). Construction methods vary, with options like cut-and-cover, bored, and immersed tunnels, each suited for different geological conditions and project requirements. Additionally, tunnels can be categorized by their location, such as underground, underwater, or mountain tunnels.
What is the purpose of the single beep emitted by a smoke detector?
The purpose of the single beep emitted by a smoke detector is to indicate that the battery is low and needs to be replaced.
What is the purpose of a breaker for smoke detectors?
The purpose of a breaker for smoke detectors is to provide a way to easily turn off the power supply to the smoke detectors in case of a false alarm or when maintenance is needed. This helps ensure the safety and proper functioning of the smoke detectors.

What are the practical applications of two hinged arch?
in the construction the arches are especially used for elevation purpose and for making tunnels also now a days these arches are useful in construction for beauty purpose
What has the author Charles Townsend Ludington written?
Charles Townsend Ludington has written: 'Smoke streams' -- subject- s -: Aerodynamics, Air flow, Wind tunnels
What is the Great American Smoke-out what is it and What is its purpose?
The great american smoke out is when the america was full of smoke and it was olluted. it was to kill off all the white moths. Happy to provide my services :)
What is a joint what is the purpose?
Something crackheads like K.B and LOS smoke! : )
What is the purpose of a smoke detector breaker and how does it function in a home's fire safety system?
A smoke detector breaker is a device that controls the power supply to smoke detectors in a home. Its purpose is to ensure that the smoke detectors are functioning properly and can alert residents in case of a fire. The breaker is designed to cut off power to the smoke detectors if there is a malfunction or if the detectors detect smoke, triggering the alarm system and helping to keep residents safe.
What is a smoke detector's function?
It detects smoke, and it acts as an early warning signal to people, it's main purpose though is it alerts people when there's smoke in side the building.
Are there tunnels elsewhere in Saskathewan other than The Tunnels of Moose Jaw?
yes there are tunnels
