Stability Analysis of Roadheaders

Abstract

-Nowadays, tunnel and underground mining drivage excavation methods have become fully mechanized. Roadheaders are one of the widely used mechanical excavation machines. They have exceptional place in this area because of their low cost and flexibilty. However they have some disadvantages such as not being used in hard and unstable formations. Improvements of this ability can cause stability problems. Therefore evaluation of stability states of these machines in different cutting conditions is vitally important. Stability analysis methods should be used for design and selection of roadheaders and when applying new technologies on them.
