Abstract:
A scientific and methodological approach has been developed to determine optimal parameters for the slopes of quarry benches and walls, based on comprehensive geomechanical studies of rock masses conducted directly in the rock masses adjacent to the quarry walls using core samples from specially drilled engineering-geological boreholes to determine the dimensions of structural blocks, the massif quality index, and the structural weakening coefficient, as well as parallel laboratory studies of the strength and physical properties of the rock. The stability of quarry walls is assessed using various calculation methods, which confirms their reliability and good convergence. Progressive parameters are recommended for bench slopes and quarry walls with a height of 300 m and inclination angles of up to 50°, provided there is a sufficient stability margin-which must meet regulatory requirements-greater than 1.3.
Keywords:
Quarry face, engineering-geological borehole, core, sample, rock strength properties, structural weakening coefficient, rock mass quality index, slope design methods, stability margin coefficient
