Types of Sensors for Environmental Monitoring

Environmental Monitoring

Environmental monitoring is required for protecting the public and the environment from pathogens and toxic contaminants and is used to prepare environmental impact assessments, as well as establish the circumstances in which human activities risk harmful effects on the natural environment. Different types of monitoring are carried out, including that of air, water and soil. Such monitoring programmes and strategies have justifications and reasons which help them establish the status of an environment or trends in environmental parameters.

There are different types of sensors used for different contaminants and for different degrees of the same. These are discussed below in detail. Many sensors have signs if you dont have one get it made at https://apexmetalsigns.com

natural environment

Types of Sensors

There are several types of sensors employed, depending on the specifications required for monitoring. Size, speed and sensitivity are all key factors to consider while choosing an environmental sensor. Sensors can be differentiated into different categories depending on the type of sensors being used, and the ecological factors an analyst is looking at.

The main types of sensors include:

Trace Metal Sensors

These include laser-induced breakdown spectroscopy (LIBS), miniature chemical flow-probe and nanoelectrode array sensor.

Radioisotopic Sensors

Radioisotopic sensors include Radiation field-effect transistor (RadFET), low-energy pin diodes beta spectrometer, cadmium zinc telluride (CZT) detectors, thermoluminescent dosimeter (TLD), neutron generator for nuclear material detection, isotope identification gamma detector, non-Sandia radiation detectors etc.

Volatile Organic Compound Sensors

Grating light reflection spectroscopy (GLRS), miniature chemical flow probe sensor, evanescent fibre-optic chemical sensor, chemical sensor arrays, gas-phase MicroChemLab, electrical impedance of tethered lipid bilayers on planar electrodes, gold nanoparticle chemiresistors, hyperspectral imaging, chemiresistor array and MicroHound sensors are all examples of volatile organic compound sensors.

Biological Sensors

Insulator-based dielectrophoresis, fatty acid methyl esters (FAME) analyser, biological sensor arrays, liquid phase MicroChemLab, μProLab are examples of biosensors.

Sensors can also be split into different types depending on environmental factors.

Moisture Sensors

Moisture sensors are used for the measurement of the quantity of water content in the soil to assess the chimerical environment in several orders of magnitude.

Pressure Sensors/Transducers

Pressure sensors operate based on the amount of pressure applied to them. They are used in industries such as aviation, automobile and hydraulic measurements and manufacturing biomedical measurements.

Tilt Sensors

The tilt sensor relates the two different axes against a reference plane which may be in two different axes. This is an essential tool for measuring tilt angles with respect to the Earth’s ground plane. Tilt sensors are most commonly used in industry and in-game controllers.

Rain Sensors

Rain sensors are simple switching devices that get activated in the event of rainfall. Rain sensors are used in water conservation devices in irrigation systems, and sometimes even in automobiles with windscreen wipers.

Vibration Sensors

Vibration sensors are crucial for acceleration and displacement with respect to the lasting impact on the environment. Displacement, velocity and acceleration are different factors that vibration sensors measure accordingly.

Tunnels: Types and Geological Investigation

Geological Investigation

Tunnels are defined as an underground route or passage driven through the ground without causing a disturbance to the overlying rock or soil cover. Tunnels are made for different purposes and are categorised accordingly.

Tunnelling has been practised on a large scale over the last two centuries in all major countries of the world for ensuring faster and better communications through roads and railways. At certain places like in high mountains, tunnelling is an absolute necessity to connect two countries or two different parts of the same country for increased access between the two locations.

Metros can also be seen as a version of tunnelling and in fact, may involve a reasonable length of tunnels as the essential component.

Excavations below the ground require very sound knowledge about the rock and soil to be excavated on the one hand and keep the tunnels safe and stable at economically viable costs for the entirety of its lifetime on the other hand. Just like roads, railways, buildings and several other construction jobs, tunnelling projects are among the most important developmental activities of a nation.

Traffic Tunnels

Traffic Tunnels

Traffic tunnels include all tunnels that are excavated for diverting the traffic load from the surface to subsurface routes for a short length for facilitating the flow of traffic at a certain speed, at minimum cost and maximum convenience. The highway tunnels, pedestrian tunnels and railway tunnels are main subgroups of traffic tunnels. A traffic tunnel is generally adopted as a convenient and cost-effective alternative to providing a direct transportation link between two places separated by immovable obstacles like mountains, water-bodies, hills or even densely populated areas in the metropolitan cities.

The Hydropower Tunnels

During the twentieth century, most tunnelling work has been in connection with hydropower generation. Such tunnels are called hydropower tunnels, and in most cases, they are driven through rocks for conveying water from one point to another using gravity to cross a hill. In such cases, they are known as discharge tunnels.

The other type of hydropower tunnels is the ones which feed water under tremendous pressure to turbines and are distinguished as pressure tunnels.

Public Utility Tunnels

Public utility tunnels include various underground excavations created for specific purposes like disposal of urban waste; for carrying cables, pipes; supplies of oil, water etc. A recent development in public utility tunnels is the construction of underground parking spaces and storage chambers in order to overcome space shortage in metropolitan cities.

Subways and tube railways can technically fall into the category of excavations as well, but they are, in all practical terms, not tunnels in the sense that they are excavations made in the ground and covered from the top later. This method of placing the tracks or tubes is called a cut and cover method and not technically tunnelling. Here the top cover remains intact and undisturbed during the excavation.

Tunnel Construction Methods And Their Comparison

Construction Methods

Tunnel construction is an underground passage constructed beneath the earth’s surface or water. In most cases, tunnel construction is expensive, but it provides comfort as well as saves time. A lot of excavation of rock or soil is required for tunnel construction. However, excavation and backfilling have become easier over the years, thanks to the availability of modern equipment. Remember when doing construction to have the correct aluminum signs around the site.

Construction Methods:

Cut and Cover Tunnelling

Cut and cover tunnelling is a prevalent technique used for constructing shallow tunnels. The advantage of this method is that it can accommodate changes in tunnel width, have non-uniform shapes and is quite commonly adopted in the construction of underground stations. Many overlapping works need to be carried out for the use of this tunnelling method. Tunnel construction, soil covering of excavated tunnels and trench excavation are three integral parts of the tunnelling method. Most of these are quite similar to other road construction projects except for the fact that the excavations involved are much more profound. Bulk excavation is undertaken under a road deck in order to reduce environmental impacts in the form of dust and noise emissions as well as minimise traffic disruption.

Drill and Blast

This tunnelling method is characterised by the use of explosives. Blast holes are drilled on the proposed tunnel surface up to a designated depth after which explosives and timed detonators are placed in the blast holes. After the blasting has been carried out, waste soil and rock are moved out of the tunnel before further blasting. Most tunnel construction done on rock involves ground which is somewhere in between two extreme conditions of soft soil and hard rock. Therefore adequate structural support measures need to be taken while adopting this tunnelling method.

Bored Tunnelling by Tunnel Boring Machines (TBM)

Bored tunnelling using a Tunnel Boring Machine (TBM) is usually used for the excavation of long tunnels. A functional TMB method requires the appropriate selection of equipment for different geological conditions and rock mass. TBM can be suitable for excavating tunnels that contain competent rocks that can give adequate geological stability for boring a lengthy section of the tunnel without any structural support. However, there is a chance of encountering extremely tough rock which can cause significant wear and tear of the TBM rock cutter and slow down the progress of the tunnelling work to the point where TBM is inefficient, uneconomical and may take a longer time than the drill-and-blast tunnelling method.

Bored Tunnelling

Sequential Excavation Method

Also known as the New Austrian Tunnelling Method (NATM), this method involves dividing the excavation location of a proposed tunnel into segments. These segments are then mined in sequential order with supports. Some mining equipment such as backhoes and road-headers are commonly used for this method of tunnel excavation. The ground to be excavated must be completely dry for applying this method, and ground dewatering is an essential process before the excavation.

How Do Miners Communicate Underground?

Communicate

The goal of any underground mine communication system is the improved local and global communications within a system which is simple to use, improving the health and safety of the workers. All of this is moving towards an integration of all the different systems into comprehensive systems which embrace people, machines, monitoring and service. MineTrax is one such example with its implementation at Fresnillo’s La Cienega mine, Mexico beginning in 2011. The Chief Information Officer of the company Baldomero Gutierrez is of the opinion that MineTrax is a breakthrough technology since it is the only underground system with wireless network infrastructure that is capable of lasting several years on a few small batteries.

underground system

Newtrax Technologies is another high-tech company based in Montreal, Canada. The company is working towards battery-powered wireless networks for texting, telemetry and tracking in regions where the installation of wires for communications and power is complicated or can endanger the lives of the people working there. The networking platform that Newtrax uses is MineTrax and is purpose-built for underground mines. In collaboration with many mining application specialists, a comprehensive list of solutions have been drawn up to improve safety, condition-based maintenance, productivity and energy management. The safety benefits of such a system are early warnings of health and safety hazards, which may be ground instability or low air quality; emergency communications in production areas in the event of a cave-in or fire, even in the hard-to-reach last mile of tunnels; faster rescue operations with the help of real-time location information on the miners trapped underground etc. The productivity benefits of the system are real-time operational intelligence which enables better optimisation of the mining process, automated data collection and reporting and early warnings of maintenance problems such as total uptime of production machinery. Social and environmental benefits include lower energy consumption which is done by turning off ventilation in areas of the mine where active diesel machinery or personnel are absent; continuous observation and logging of operating parameters which enable verification of their compliance with commitments, and better competitiveness means better chances of maintaining jobs even at low prices.

network infrastructure

The backward compatibility and simplicity of the MineTrax system are extremely valuable. It has a network infrastructure comprising battery-powered, wireless and self-organising nodes which were designed to last years on just a few small D cell batteries. Another essential feature of MineTrax is that it can also inter-network with both narrowband such as leaky feeder, through-the-earth etc. and broadband like fibre, coaxial cable etc. having backhaul links to the surface, which provides better adaptability and flexibility to heterogeneous mine sites. So miners need to be able to use both wired as well as wireless communication system in the chance that either one of them fails.
