Types of Sensors for Environmental Monitoring

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 Types of Sensors There are several types of sensors employed, depending on the specifications required…

Tunnels: Types and Geological Investigation

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…

Tunnel Construction Methods And Their Comparison

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…

How Do Miners Communicate Underground?

How Do Miners Communicate Underground?

Miners 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. Newtrax Technologies is another high-tech company based in Montreal, Canada. The company is working towards battery-powered wireless…
