The Mining Surveying Department performs a wide range of tasks: it takes part in drawing up plans for the development of a deposit, monitors compliance with design decisions during the construction of a quarry, deals with issues of monitoring the movement of a rock mass, calculates production volumes and supports drilling and blasting. In this regard, the issue of automation of daily mining surveying tasks is acute. To date, there are technologies that allow to automate most of the daily tasks of the mining surveying service and bring economic benefits to the enterprise. Such technologies include systems for positioning the working bodies of mining equipment – a set of sensors and controllers installed on a working machine. These systems are already actively used abroad and in some Russian road construction companies. The aim of the work is to increase the efficiency of the mining surveying service in open-pit mining by introducing a positioning system for mining equipment. The article deals with the issue of using in the production of systems for positioning the working bodies of mining equipment in order to update mining surveying plans and digital surface models. The accuracy with which these solutions can work is calculated.
