are more crack and wear resistant by the use of flex-acceptable materials and welding techniques. Based on a detailed geotechnical baseline report, the cutterhead design can be optimized by conducting full-scale laboratory linear cutting tests. ROSTAMI and OZDEMIR [45] proposed a method to calculate the thrust forces based on linear cutting tests; however, the rock strength tested ranged from 70......

and the geodynamic relationship between crust-mantle reaction and mineralization in south China were revealed. Progressive metallogenic models of certain typical ore deposits were established based on the study.... Since 2000, we have independently developed the "Diwa Theory", Shell Geotectonics, "Pseudo Random Signal Coding Electrical Method" and multi-factor complex metallogenesis. Based on the theories, it has......
