Assessment of Blasting‐Induced Ground Vibration in an Open‐Pit Mine under Different Rock Properties

Abstract: In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blasting vibration is necessary to ensure slope stability. In this study, the blasting vibration signals monitored at a blasting site with different rock masses were used to investigate the attenuation characteristics of blasting vibration through the peak particle velocity (PPV), frequency characteristics, and energy distribution of the bla… Show more

“…At present, many countries have reconstructed and used underground goafs as human living and working places. For example, the United States once converted an old mine with a depth of 2,000 meters underground into a laboratory; France built the Haute Marne laboratory 500 meters underground to store nuclear waste; Japan's Shiroyama Underground Hydropower Station was built at a depth of 200 meters underground; the sewage treatment plant under the Helsinki Base in Finland is located at a depth of 100 meters underground [1][2][3][4]. As an excellent natural protective material, natural rock has the advantages of hard texture, high carrying capacity, and good durability [5].…”

“…e strength of the coal body is low, and the coal seam is prone to large deformation under the action of vertical pressure. e coal seam is liable to slip and deform along the weak side of the coal-rock interface toward the roadway, causing a large series of deformation and shrinkage and then a series of deformation failure modes such as roof sinking and floor bulging [1][2][3][4][5][6][7].…”

“…Huang et al [5] and Martin and Chandler [6,7] proposed a CWFS model for deep rocks by analyzing the results of indoor tests on a large number of granite mechanical properties. Yang et al [8], Yin et al [9], and Yin et al [10] conducted a large number of cyclic loading and unloading tests on Jinping deep-buried marble specimens and investigated influence factors such as the rate of unloading confining pressure, initial damage, and unloading path on damage characteristics to establish a unified strain energy criterion for homogeneous isotropic hard rocks. Feng et al [11] examined the Jinping Underground Laboratory Phase 2 deep buried tunnel using digital borehole equipment and proposed a data evaluation method for digital borehole observations based on a rock mass integrity index for analyzing the fracturing process of deep buried hard rock subdivisions.…”
