Zusammenfassung:Thermally Stable Diamond Composite (TSDC) has been used to make rock cutting tips to tackle the challenges of high cutting temperature and high abrasiveness met in hard rock cutting. Various research has been conducted to investigate the failure behaviour and predict the failure risk of the TSDC tips in real rock cutting operations. Based on the scenario of roadway development in underground coal mines, a series studies have been carried out to estimate the probability of TSDC tip sudden failure suffered from randomly occurring excessive bending force, which is one of major failure modes of the TSDC tips. This study aims to improve estimation accuracy of the failure probability by removing the constraint on roof rock thickness that has been adopted in existing research.
