Abstract: The article presents an analysis of the working conditions of the mining equipment, presents an assessment of the functioning of electronic devices and communication facilities underground, and formulates the main functional and nonfunctional requirements to the inertial positioning system of geokhods. For this purpose the analysis of natural factors indirectly or directly influencing the operability of inertial positioning systems is carried out. The basic demonstration sample of a geokhod, which is the main element of a mobile robotic tunneling complex, with a description of the principle of operation and possibilities of its work is presented. Existing analogues and currently used technologies for determining the position of equipment in space are considered. The basic characteristics of inertial positioning systems selected as analogues are singled out. Comparative characteristics of existing inertial positioning systems are presented. The concept and working principle of specialized tunneling equipment are discussed. On the basis of the analysis the main functional requirements to the system of inertial positioning of geokhods are formulated. The results of the development of the laboratory prototype of the system of inertial positioning of mining machines are presented. The components minimally satisfying the necessary requirements are selected. Model for the technology of data acquisition from the tunneling equipment and for the information receiving board on the operator's computer is simulated. A general layout electric component designed for reading out, sending and receiving parameters from the equipment and for the complete functioning of the system was made. Programs are written to read and process the input data, transfer them to the operator's device and display them in graphical format. On the basis of the developed laboratory model the goal and objectives of further research are formed.
