The application of the analytic hierarchy process when choosing layout schemes for a geokhod pumping station

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.

“…A basic feature of the geokhod is the screwing into the contour strata of the body which performs the function of the mobile support. At the same time, the force providing motion and balancing the reaction from the technological operations is formed not by friction forces at the media interface (soil-crawler mechanism) or repulsion from an artificially constructed support element (hydraulic jack-permanent support), but as a result of introducing the propulsion elements in the contour strata and the use of a normal reaction arising from the interaction of the elements of the geokhod with the rock mass [5][6][7][8].…”

Abstract. The article presents the power dependencies for determining the number of blades of the cutting body of geokhod for destruction of rocks of low hardness. The obtained dependences are based on the developed method of calculation of the blade cutting body of the geokhod. The presented dependences make it possible to choose the rational number of blades of the geokhod cutting body. The intensity of the development of underground space by the countries of the world community, including Russia, is increasing. In this connection, the tasks are to increase the rate of development and to reduce the cost of work.

Abstract. The article proves the necessity of creating a control system for the geohod. The scope of application of the geohod is described. The general scheme of the geohod with the main structural elements -cutter drum, head and tail sections, external mover -is described. Enlarged tasks that need to be addressed when creating a control system for the geohod are identified. The tasks of motion control of the geohod in the geomedium, improving the efficiency of the geohod, positioning the geohod in space, control of the support systems, diagnostics of the condition of the geohod, interaction of the control system with the operator are described. The directions of further research are identified: to formulate the requirements for the geohod control system; to analyze tasks solved by the geohod control system; develop the structure, mathematical models and algorithms for the operation of subsystems of the geohod control system; to develop software to simulate the interaction of subsystems of the geohod control system with each other, with the geomedium and the operator.
