Semantic segmentation of underground mine roads is very important to efficiently obtain road information from images. The boundary not obvious, the environment complex, and identification difficult. In order effectively realize accurate roads, a network model using deep learning technique proposed. Choosing BiSeNet as basic framework, adopting unified attention fusion module, channel spatial en...

Spatial data mining is the process to mine data from spatial data sets like OpenStreetMap or any kind of geographic data. With the emergence of time, Geographic Information get more value from the researchers. This is used to mine useful data and features based on different locations. In related work, existing techniques are based on Dijkstras algorithm and Euclidean distance for spatial data m...

BACKGROUND Thirty-one cases of mesothelioma resulting from exposure to Libby Asbestos have been identified from Libby, Montana. Eleven cases not previously reported are the subject of this report. METHODS These cases are in non-occupationally exposed people, appearing to have resulted from exposure to contamination of the community, the surrounding forested area, and areas in proximity to the...

Demersal trawling causes significant impact on marine benthic habitats including sediment biogeochemistry and faunal composition. To examine the effect of shrimp trawling on benthic sedimentary habitats a replicated Before/After (B/A) experiment was performed in the Gullmarfjord, Western Sweden, after 6 years protection against trawling activities. The experimental area was randomly divided int...

Mining of copper and gold at Kansanshi is done in the Main North West pits using hydraulic excavators a mining fleet haul trucks. In recent past, there has been reduced truck deployment, increased shovel waiting time, production grade/quality ore delivered to crushers. Therefore, need improve productivity optimise operations mining, loading hauling. This paper focuses on use High Precision (HPM...

This paper describes technology (hardware and software) that has been developed to estimate the volume of material contained within the tray of various haul trucks. Such information is critical to truck utilization and thus can provide information that could lead to significant gains in productivity. The system consists of a field computer and two proximity lasers. The lasers are placed high ab...

This study investigated the phenology, patterns of haul-out habitat use and distribution of the grey seal around Cornwall and the Isles of Scilly. A full census of the coast was carried out by boat over 4 days, in order to make a full count of seals hauled out and close to the coast, and to document all haul-out sites. Regular land-based surveys were made of three haul-out sites in Cornwall, to...

Many factors influence the fatigue state of human beings, and has a significant adverse effect on health safety haulage operators in mine. Among various monitoring systems mine operations, currently, Percentage Eye Closure (PERCLOS) is common. However, work other environmental haul truck drivers; PERCLOS do not consider these their modeling fatigue. Therefore, factors’ impact individual operati...

In this paper we assess the impact of the CO2 costs for shortand long-haul aircraft based on present values and on purchase options. We evaluate purchase options with a framework developed for real option analysis to estimate the value of flexibility under uncertain kerosene and CO2 prices. We find an average influence of CO2 costs on present values of €1.1 million for the short haul plane and ...

Most autonomous navigation systems used in underground mining vehicles such as load–haul–dump (LHD) and trucks use 2D light detection ranging (LIDAR) sensors representations/maps of the environment. In this article, we propose 3D LIDARs existing simultaneous localization mapping (SLAM) jointly with methods to produce or update grid maps tunnels that may have significant elevation changes. Exist...
