Abstract:
Rock mass quality grading is important basic work to judge the rock mass quality and guarantee safe and reasonable mine engineering.Stereoimaging technology is used,the rock mass image information is analyzed and 3D point cloud information is recognized.The rock mass structural face distribution is obtained by analyzing point cloud spatial 3D information.Based on rock mass surface image information analysis,the joint morphology and weather-ing conditions are obtained.The joint rock mass quality rapid grading method is proposed based on RMR,whose feasibility has been discussed in the case study of joint rock mass.The method can provide reference for preliminary rapid judgment and application of rock mass quality grading.
