Unique research can save lifes in mines


The result of a research study performed by Rickard Hansen at Mälardalen University (MDH) in Sweden can lead to improved fire safety and evacuation safety of the mining personnel. The most common form of subterranean fires is vehicle fires in mines. Richard Hansen has in his research found out how to predict how these fires behave and develop.

Until today there have not been any extensive and in-depth studies regarding fires in mines, except for coal mines. Rickard Hansen is now changing this through his doctoral thesis "Study of heat releases rates of mining vehicles in underground hard rock mines”.

In his study of fire safety in underground mines, he demonstrates the possibility of calculating the total fire effect for mining vehicles

- These are results that society can benefit from, foremost when designing different fire rescue systems in the mines, such as mobile refuge chambers, stationary refuge chambers and smoke evacuation fans.

The air supply of the mobile refuge chambers and the stationary refuge chambers can be made larger to last longer. One could also increase the number of fans, place them closer together and make them stronger.

Thanks to this new knowledge we can improve the capacity and location of the system. This means increased fire safety and evacuation safety of mining personnel. The results could save lifes, says Rickard Hansen.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
