Once segmentation of 3D surface data of a rock pile has been performed, the next task is to determine the visibility of the surface rocks. A region boundary-following algorithm that accommodates irregularly spaced 3D coordinate data is presented for determining this visibility. We examine 3D surface segmentations of laboratory rock piles and determine which regions in the segmentation correspon...

by increasing demands on paper products and shortage of fiber resources, various strategies were introduced to meet the requirements. in this context, application of mineral fibers is a novel and growing approach. this study was aimed to reduce the plant fibers by application of, mineral fiber in the papermaking system. application of 0, 10, 20, and 30% loadings of rock wool mineral fibers (rwm...

The cable plays a vital role in roadway support. As the last barrier to prevent roof collapse and impact disaster accidents, it is of great significance study stress characteristics cables under dynamic load guide rock burst With high-strength Φ21.6 Φ21.8 mm low-resistance high-extension Φ21.5 as examples, this paper studied instantaneous mechanical state energy dissipation different types load...

Coal mining activities have intensified, and underground depths increased, posing significant challenges for mitigating rock burst hazard. To address this issue, paper proposes an improved comprehensive weighting prediction (CF-TOPSIS) method that predicts weight grade indices evaluation. The study introduces a novel variable coefficient to optimize the conflict response problem employs correla...
