The rock breaking and ROP increase mechanisms for single
Torsional impact drilling is a new technology which has the advantages of high rock-breaking efficiency and a high rate of penetration (ROP). So far, there is no in-depth understanding of the rock-breaking mechanism for the ROP increase from torsional impact tools. Therefore, it has practical engineering significance to study the rock The rock-breaking efficiency of a drilling tool directly affects the production costs and progress of foundation construction. It is essential to understand the mechanism of mechanical rock-breaking to improve rock-breaking efficiency. In this study, dynamic rock-breaking simulation research was carried out on a drill bit and was based on the LS Numerical Simulations and Experiments on Single-Tooth Rock-Breaking

A hard rock narrow reef mining machine—ARM 1100
• The machine should excavate the maximum amount of reef from a single set-up • The machine in operation must be flexible enough to follow the major reef undulations •All rock cuttings must be removed from the immediate cutting area and then transported out of the stope. Figure 1. Theoretical rock breaking process for conventional Rock mass conditions are extremely sensitive to tunnel boring machine (TBM) tunneling. Therefore, establishing a surrounding rock excavatability (SRE) classification system applicable to TBM tunnels. Accurately and intelligently identifying excavatability grades can also facilitate efficient TBM tunneling and intelligent Applied Sciences Free Full-Text Study on the Classification
