Application of Multi-Criteria Decision Analysis for Choice Geokhods Cutting Head

The article deals with the choice of cutterheads for Geokhod in the early development stages. Early development stages are characterized by the lack of quantitative characteristics, such as cutting forces, weight, feed forces, etc. In this case, the choice is made on the accordance of the cutterheads with the requirements for them. Under such conditions were determined the most appropriate method of multi-criteria analysis for the choice of the cutterheads – “ELECTRE III”. The results of the use of this method are established the most fully meet the requirements cutter heads: a rotary, drum, and head with fixed heads

Estimation of the Overall Dimensions of the Outer Elements of Geokhod

The article considers the question of determining the possible dimensions of the outer grooves of different diameters Geokhods. Taking into account rock properties and destination of outer elements of Geokhod set the height of the outer grooves. The thickness of the outer element is determined by the conditions of their required strength. The set values can be used to develop circuit solutions of outer cutting drums of Geokhod
