Abstract.This study aimed to investigate the impact of partial rupture of the anterior cruciate ligament (ACL) on the stress distribution within the meniscus and cartilage of the knee joint using finite element analysis. The findings provide a theoretical foundation for the clinical prevention and treatment of ACL injuries. The anteromedial bundle of the ACL is crucial for maintaining valgus stability in the knee during standing with the knee in extension. A reduction in valgus or rotational stability leads to a redistribution of stress within the joint, making the meniscus, as a cushioning structure, … Read more →

Abstract.To address dynamic hazards such as coal and gas outbursts and rockbursts during deep mining, this study takes a certain Coal Mine as the research subject. A mine-wide microseismic monitoring network was established using the Polish SOS microseismic monitoring system. By collecting, transmitting, and processing microseismic data in real time, the spatiotemporal distribution characteristics of microseismic events were analyzed. A dynamic hazard early warning model was developed based on the microseismic data, and targeted prevention measures were formulated in combination with the warning model. … Read more →
