The paper examines the technological scheme for granite mining with the use of rock chutes in the conditions of the Rybalsky Quarry. The research purpose is to substantiate effective technological schemes for mining the upper granite quarry horizons to reduce mining costs and improve the final product quality. Research is conducted using: the method of scientific analysis, theoretical research and practice of project and production organizations; mining-geometric calculations; variant method for comparing and selecting technological schemes for mineral mining. As a result, the dependence of the transportation cost of 1 ton of mineral on the transportation distance has been determined, due to which it became possible to assess the effectiveness of using rock chutes in the conditions of the Rybalsky Quarry. The dependence of the rock chute inclination angle on the friction coefficient when rolling down the mined mass has been revealed, which substantiates the rational inclination angle of the rock chute for quarry conditions. Practical value of the research results consists in reducing the cost of transporting minerals from the upper quarry horizons by applying a technological scheme with the mined mass movement using rock chutes. |
