The state of the issue of the relevance and efficiency of the technology of using liquefied natural gas as a partial replacement of diesel fuel in mining vehicles is considered. It is argued that this technology does not require complex and time-consuming re-engineering of internal com- bustion engines, which makes it economically feasible. It is noted that liq- uefied natural gas seems to be the most promising alternative to petroleum motor fuels in heavy-duty mining dump trucks. The use of liquefied natu- ral gas as a motor fuel reduces the environmental burden; increases the energy efficiency of the rock mass hauling process and reduces fuel costs. It is said that developments aimed at substantiating and choosing design and layout solutions for the placement and arrangement of cryogenic equipment on mining vehicles are relevant. The new method for installing cryogenic fuel tanks on the deck of the BelAZ 7513 series mining dump truck with a payload capacity of 130 tons is described in detail. Layout so- lutions for the modernization of the deck of the BelAZ 7513 series dump truck allowing placing additional cryogenic equipment on its board are presented. The data presented indicate that the successful implementation of the proposed method is confirmed by the project on equipping the BelAZ 75131 mining dump truck with cryogenic onboard fuel systems, implemented in practice.
