A kind of control technology for squeezing failure in deep roadways: a case study

Geomatics, Natural Hazards & Risk, 2017
Under high horizontal ground stress, the squeezing failure has been a common failure pattern for deep roadway. And the large deformation of surrounding rock mass around the roadway has also been a major challenge for deep mining practices.

Composite grouting reinforcement technology for deep roadway surrounding rock

Gong-kuang zidonghua, 2022
The single grouting method and grouting material can not achieve an ideal grouting effect under the complex geological conditions of deep roadway surrounding rock. In order to solve this problem, a composite grouting reinforcement technology for deep roadway surrounding rock is proposed.

Mine roadway personnel counting technology based on deep learning

Meikuang Anquan, 2023
When a safety accident occurs in a coal mine, it is necessary to clearly understand the personnel situation in each area and reasonably arrange the rescue plan. In this paper, YOLOv5 is used as the target detector, combined with the improved DeepSORT tracking algorithm to track the mine personnel, and the personnel count in each roadway area of the ...

Bilateral Supracondylar Process in a Subadult in the Late Antique Age: A Case Report

Archaeometry, EarlyView.
ABSTRACT During the excavation procedures for the railway trait Napoli‐Cancello, in the city of Afragola (Naples), several burials dating back to the Late Antique Age were found. One of them was an amphora burial (enchytrismòs) and contained the skeletal remains of a subadult individual affected by bilateral supracondylar process. Supracondylar process

UrbanClipAtlas: A Visual Analytics Framework for Event and Scene Retrieval in Urban Videos

Computer Graphics Forum, EarlyView.
Abstract Extracting actionable insights from long‐duration urban videos is often labor‐intensive: analysts must manually sift through raw footage to pinpoint target events or uncover broader behavioral trends. In this work, we present UrbanClipAtlas, a visual analytics system for exploring long urban videos recorded at street intersections ...
