In the first section, the tunnel was excavated with higher torque and thrust as well as low penetration rate and rpm, leading to higher cutter consumption.

The invention discloses an advanced geological prediction method for underground engineering. With geology as pivot, the advanced geological prediction method for underground engineering comprises four stages of long-term advanced geological prediction, middle-term advanced geological prediction, short-term advanced geological prediction and impending advanced geological prediction.

The Bilihe gold deposit is located in the collision belt between the southern margin of Central Asia Orogenic Belt (CAOB) and the northern margin of North China craton (NCC) ().The CAOB, as the world’s largest site of juvenile crust growth in the Phanerozoic, formed by subduction–accretion processes within the paleo-Asian Ocean from the end of Mesoproterozoic to late Paleozoic (e.g., Jahn.

The book is published in two volumes, with the second volume covering both theoretical themes like design basics, geological engineering, structural design of tunnels and monitoring.The Llao Rock flow is one of the most interesting of the region and is the most conspicuous.

Its general outline in cross section filling a valley of the rim may be clearly seen (Pl. IX, A) across the lake. The flow is more than a mile wide along the crest and over 1, feet.

1. Introduction. The geological conditions for tunnel boring machines (TBMs) have become much more severe and complex with the ever-increasing tunnel construction activities around the world [, ], such as railway tunnels [, ], highway tunnels [], metro tunnels [, ], and water tunnels [].For long-distance TBM excavation in full-section hard rock formations, cutter tool wear is severe.
