INVESTIGATION OF THE NEED TO ADJUST THE ROADS DESIGN STANDARDS OF IN QUARRIES

Abstract

The purpose of this work is to justify the need to adjust the standards for designing roads in quarries, taking into account the Rules of labour protection in the development of minerals in an open way. The study is based on domestic (experience in Poltava GOK, Yeristovsky GOK) and foreign (mining enterprises in Australia, USA, Canada) practical experience in operating heavy-duty mining vehicles, as well as on a systematic analysis of current norms for technological design of roads in quarries. An analysis of the regulatory and legal issues related to the safety of operation of heavy-duty mining vehicles showed that the Ukrainian standards for designing roads in opencast mines have not changed 25 years. At the same time, the fleet of technological dump trucks used in quarries, technical characteristics, capabilities and prospects for their use, have significantly changed. The study and identification of the advantages of using roads with a constant slope without the installation of horizontal platforms provides the basis for developing recommendations for updating the design standards for roads in open pits, as the current standards do not meet the requirements for the safe operation of modern heavy-duty mining vehicles. It is proposed to update regulatory legal acts by reviewing them with corrective amendments, taking into account the appropriate level of safety when using heavy trucks. Implementation of the proposed standards to improve the transport scheme of the quarry will contribute to the safe operation of heavy mining vehicles.
