Metallurgical aspects of rock bolt environment fracture

, 2005
The aim of this research was to understand the Stress Corrosion Cracking (SCC) of rock bolts. The laboratory tests have produced fracture surfaces similar to those from service.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Suture fixation of traumatic rib fracture flail segment with Klebsiella osteomyelitis

Trauma Case Reports
We report the case of a 71-year-old male who initially presented with urosepsis and was found to have a rib fracture of his right 6th rib with a flail segment and an associated abscess. Given the concern for infection, surgical rib fixation with titanium

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Development and Evaluation of a Nurse Practitioner-Led Revised Rib Fracture Pathway to Reduce Length of Stay and Pulmonary Complications

Rib fractures and thoracic trauma account for nearly 15% of trauma patients requiring hospitalization and a quarter of all traumatic deaths in North America (Butts, et al., 2021). Additionally, rib fractures are associated with a complication rate of up

Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

Deep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

Attempted repair of chest wall injury following penetrating injury with surgical stabilization rib and autologous bone graft: A case report

Trauma Case Reports
Rib fractures are one of the most common injuries following blunt trauma. When associated with penetrating trauma, the projectile velocity and immense energy transfer cause significant rib fracture displacement and fragmentation.
