Abstract: Microplastics (MPs) have been recognized as one of the biggest environmental challenges in marine ecosystems. Despite the extensive existing research knowledge on MPs, the origin, transport and deposition of MPs in beach sediment is still unclear. This review highlights the global occurrence, spatiotemporal distribution, sources, transport and accumulation of MPs on about 1700 world’s beaches, exploring the existing connotions on... More

Abstract: Geological anomalies, including faults, fractured zones, and collapse pillars, pose serious threats to mining safety by increasing the risk of water inrush and roof collapse. To enable accurate ahead-of-face detection, this paper presents the development and practical application of a single-borehole impulse radar (BHR) system specifically designed for underground coal mine environments. The system incorporates... More
