The stability control of fissured rock is difficult, especially under static and dynamic loads in deep coal mines. In this paper, the mechanical properties, strain rate evolution energy dissipation anchored rocks were respectively obtained by SHPB tests. It was found that bolt can provide supporting efficiency-improving effect for against disturbance, increased quadratically with decrease anchoring angles. Then, mechanism slipping model. Furthermore, energy-absorbing instantaneous...
Abstract Rheological mechanical properties of the soft rock are affected significantly by its main physical characteristics-clay mineral. In this study, taking mudstone on roof and floor in four typical mining regions as research object, firstly, clay mineral characteristic was analyzed X-ray diffraction test. Subsequently, rheological samples under different confining pressures studied through triaxial compression creep tests. The results show that content is different, which leads to...
The construction of accurate and interpretable predictive model for high abundance fishing ground is conducive to better sustainable fisheries production carbon reduction. This article used refined statistical maps visualize the spatial temporal patterns catch changes based on 2014-2021 fishery statistics Japanese sardine Sardinops melanostictus in Northwest Pacific Ocean. Three models (XGBoost, LightGBM, CatBoost) two variable importance visualization methods (model built-in (split) SHAP...
This research proposes using a neural network to detect and identify the landmark points of carapace Chinese mitten crab, with aim improving efficiency in observation, measurement, statistics breeding sales. A 37-point localization framework was developed for carapace, dataset augmented through random distortions, rotations, occlusions enhance generalization capability. Three types convolutional models were used compare detection accuracy, ability, model power consumption, different loss...
Understanding the spatial pattern of human fishing activity is very important for fisheries resource monitoring and management. To understand distribution tuna purse seiner operations in western central Pacific Ocean its relationship with marine environment, this paper uses AIS data Tuna seiners from 2015 to 2020 excavate effort information, which combined 24 environmental factors same period, including sea surface subsurface levels using boosted regression trees (BRT) model general additive...
Understanding the spatial pattern of human fishing activity is very important for fisheries resource monitoring and management. The environmental preferences tropical tuna purse seine fleet in Western Central Pacific Ocean (WCPO) were constructed compared at different scales based on effort (FE) data from available automatic identification system (AIS) commercial fishery compiled Fisheries Commission (WCPFC), using maximum entropy (MaxEnt) methods. MaxEnt models fitted with FE remote sensing...
Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists fishery managers. Although China has applied Beidou vessel position monitoring system (VMS) to manage trawlers since 2006, little known regarding impacts on sea bottom environments. In this study, continuous VMS data 1403 single-rig otter registered in Xiangshan Port, 3.9% total China, were used map effort 2013. We accumulated distance (AD),...
Ecological fishery management requires high-precision information to support resource and marine spatial planning. In this paper, the Automatic Identification System (AIS) was adopted extract on fishing grounds of light purse seine vessels in Northwest Pacific Ocean. The distributions mapped by data mining, kernel density analysis hotspot methods were compared. similarity index applied determine consistency between computed fisheries information. Finally, derived best method used investigate...
Inland all-electric ship is receiving more and attention due to its advantages in terms of low carbon, energy conservation, flexibility operation mode. However, extensive promotion application are held back by various problems such as long charging time, high cost supplement, environmental factors, etc. In addition, the complexity electric fleet also poses a challenge optimal operation. Hence, an voyage scheduling model inland fleet, with departure time speed each decision variables, firstly...
To understand the spatial temporal distribution characteristics of Illex argentinus caught by trawl fishing vessels in Southwestern Atlantic Ocean and their relationship with key marine environmental factors, this study analyzed changes ground center at ten-day scale from December 2019 to May 2022, combining Chinese log data satellite remote sensing data. Utilizing Maxent model, intervals were used as scale, ten including sea surface temperature, height, salinity, chlorophyll concentration,...
Information and understanding of fishing activities at sea is important to fisheries science, public authorities policy-makers. To understand the spatial–temporal distribution characteristics squid-jigging vessels how marine environment affects in North Pacific Ocean, operation behavior was analysed by using factors environmental factors. The effort (FE) information calculated based on automatic identification system (AIS) data Ocean from July November 2017 2020, overlay maps spatial were...
In open ocean environment with rich biodiversity, the assessment of fish resources is critical to development marine ecosystems and sustainable use resources. Environmental DNA (eDNA) metabarcoding a new, constantly evolving tool has recently been used examine deep-sea eukaryotic diversity communities. Here, eDNA was monitor populations in central Pacific Ocean understand distribution biodiversity region investigate abundance dominant species. Water samples present study were collected from...
The refined monitoring and identification of fishing operations by vessels is great significance value to vessels.
