Ground-Penetrating Radar for Karst Detection in Underground Stone Mines

The purpose of this work is to demonstrate the use of GPR in an underground stone mine and to discuss the importance of karst void detection ahead of Another reason for European mining decline is the negative public environmental perception of mining (e.g. Kivinen et al. 2020), which makes it difficult for small and medium-sized enterprises in particular to build a business case and to acquire relevant consents.

Applying MMD Data Mining to Match Network Traffic for Stepping-Stone

MMD data mining algorithm was applied to estimate the length of a connection chain to detect a stepping-stone intrusion [ 6, 7 ]. However, to the best of our knowledge, it is the first time we propose to apply MMD data mining algorithm to match network traffic. The experimental result is encouraging.To tackle the challenges posed by dense small objects and fuzzy boundaries on unstructured roads in the mining scenario, we proposed an end-to-end small object detection and drivable area segmentation MineSDS: A Unified Framework for Small Object

Detecting stepping‐stone intrusion using association rule mining

In our previous study 27, we used association rule mining to discover stepping‐stone attacks and found that the reasoning behind the use of association rules was promising. Besides, Kuo, and Huang 30 and Almulhem and Traore 31, 32 denoted the stepping‐stone detection as an association rule‐mining problem. Their results indicated Exposed stones in sandy sublittoral environments are hotspots for marine biodiversity, especially for benthic communities. The detection of single stones is principally possible using sidescan-sonar (SSS) backscatter data. The data resolution has to be high to visualize the acoustic shadows of the stones. Otherwise, stony substrates will not be Geosciences Free Full-Text Detection of Stones in Marine

Ground-Penetrating Radar for Karst Detection in Underground Stone Mines

The Mine Safety and Health Administration (MSHA) currently lists 116 active underground stone mines in the USA, and the vast majority of which extract limestone for crushed stone products. These limestone mines have the potential to encounter karst voids at some point in their operation, as most karstic regions of the USA develop in The seismic detection is likely to be affected by the noise, and cannot delineate the low velocity layer under the high velocity layer and the shallow layer (less than 50 m) 4.Application of electrical resistivity tomography (ERT) for rock

Detection of Objects Dangerous for the Operation of Mining

Experiments were carried out in which the results of the use of the following neural networks were checked: RetinaNet, Mask RCNN and YOLOv5. A brief comparison of these architectures is e.g., in [5, 16].3.1 RetinaNet. RetinaNet is a one-shot object detection model that utilizes anchor boxes and focal loss to handle the class By operatin in coincidence with the original 10-meter reflector, the sensitivity for gamma-ray detection will improve by more than an order of magnitude.

(PDF) A review of GPR for landmine detection

The rate at which a mine detection system falsely identifies man-made or natural clutter objects as mines is referred to as the system's false alarm rate (FAR). Generally expressed as a rate perA long interactive TCP connection chain has been widely used by attackers to launch their attacks and thus avoid detection. The longer a connection chain, the higher the probability the chain is exploited by attackers. Round-trip Time (RTT) can represent the length of a connection chain. In order to obtain the RTTs from the sniffed Applying MMD Data Mining to Match Network Traffic for Stepping-Stone

Review of preventive and constructive measures for coal mine

It was extensively tested by Cybulski [1] with over 1700 tests at Barbara experimental mine, Poland. The stone dust was kept on shelves for their easy dispersal. Construction and maintenance of shelf-type Polish stone dust barriers in mines is a labour intensive and costly affair. (2) Stone dust bag. Download : Download high-res image In this study bending and shear fracture experiments on healthy and adhesively repaired granite samples with concurrent acoustic emission (AE) monitoring are discussed. AE can characterize the difference between the fracture modes using simple features analysis based on the activity of the early loading. It is the first time that such a Acoustic emission monitoring of granite under bending and

Ground penetrating radar and imaging metal detector for antipersonnel

We have chosen to concentrate our first experiments on a commercial impulse ground penetrating radar with a 1 GHz antenna and a metal detector used for imaging purposes. The metal detector should help to distinguish two objects with similar radar echoes but different metal content, e.g. a mine and a stone of the same size.Detection of damage processes and construction of damage constitutive model in granite by sound signals.
