摘要：The advancement of intelligent mining in open-pit operations has imposed higher demands on geological transparency,aiming to provide a robust foundation for intelligent drilling and *** this study,a linear array of 120 nodal seismometers was deployed along the surfaces of the C8 and C9 platforms at Fenghuang Mountain to investigate cavities within the rock mass and prevent improper intelligent *** seismometers were 1 m apart along measurement lines,with a 2-m spacing between lines,and the monitoring time for each line was set at 2 *** deployment was paired with spatial autoco.relation and station autoco.relation to analyze ambient noise seismic data and image the velocity and structure within the rock *** results demonstrate that the locations and sizes of cavities or loose structures can be accurately identifi ed at the prepared excavation *** with traditional geological exploration methods for openpit mines,the approach in this study off ers higher accuracy,greater effi ciency,reduced labor intensity,and insensitivity to water *** noise seismic imaging for detecting adverse geological co.ditions in open-pit mines provides critical insights and references for intelligent mining advancements.
