tunnel mechanics

KAMY is the worldwide leader in manufacturing hydraulic cutters, road headers, tunnel support systems, and other specialized machinery used in the tunneling, mining, and construction industries. Through KAMY’s years of experience and innovative thinking, we can provide custom engineered solutions for nearly any project requiring rock excavation or concrete demolition.

KAMY is the leading manufacturer of roadheaders in the weight class of 13-80 tons weight. Our roadheaders offer interchangeable cutter heads, both transverse and axial and are custom engraved for each project. Our hydraulic cutters are suitable for material with uniaxial compressive strength ranging from 500 to 25,000 pounds per square inch. All of our products can be utilized in a variety of applications from rock excavation, trenching, demolition and concrete, to underwater cutting, tunneling, and scaling.

Lecture 20: Quantum Tunneling of Electrons

The main effect of quantum tunneling is to enhance the reaction kinetics, by allowing particles to sometimes tunnel through the barrier from a lower energy, rather than diffusing randomly over the top, as required by classical statistical mechanics.
