“…Moreover, the intensity of the replacement reaction between magnesium sulfate leaching solution and the ionic rare earth ore body directly affects the percolation coe cient of the solution. A higher percolation coe cient results in a more rapid degradation of the strength of ionic rare earth ore body (Silva et al, 2022). As shown in Fig.…”

“…Based on blast damage zone thickness weighting factor and the existing stability map, a stability model is proposed to estimate the FOS of slopes with different slope geometry and rock mass properties. Taking Daye Iron Mine as an example, Jiang et al [18] established a three-dimensional numerical model of underground mining in open-pit mine, and studied the influence of underground mining activities on the blasting vibration attenuation of open-pit slope. The influence of blasting vibration on the open-pit slope of underground mining is also discussed.…”

Blasting mining in open-pit has a significant impact on the adjacent slope, which often causes the rock mass cracking and spalling of the slope to form a landslide disaster. In order to explore the impact of blasting vibration on the adjacent slope, field tests were carried out with professional testing equipment, and several blasting vibration data were measured. Sadovsky formula was used for fitting analysis, and the influence coefficient of blasting vibration was obtained. The slope stability analysis was carried out by using the limit equilibrium SLIDE analysis software, and the slope safety factor under the influence of blasting vibration was obtained. The results show that: The maximum blasting vibration speed monitored in this blasting is 2.1987 cm/s, and the main vibration frequency is 14.6484 Hz. Therefore, according to the standards in the regulations, the impact of this blasting on the slope meets the corresponding requirements. In this slope stability analysis, the blasting vibration influence coefficient Kc= 0.032, when 40 m away from the final slope is used. Morgen Prince method and Spencer method generally have higher safety factors than Bishop method. The safety factor of the analysis section at the 45° slope angle is 1.217. The slope can maintain stability under the influence of blasting vibration.
