Abstract:

(Uploaded by Plazi for the Bat Literature Project) As a part of an inventory of bats in abandoned mines at the municipality of Guanacevõ´, Durango, Mexico, a sample of long-eared bats (genus Corynorhinus) was collected and ectoparasites were taken. Twenty-three specimens of Corynorhinus mexicanus Allen, 1916, and 18 of Corynorhinus townsendii (Cooper, 1937) were collected in four sampling periods coincident with the seasons. In total, 98 ectoparasites of 10 species and seven families were examined. Five species are recorded for the Þrst time on C. mexicanus and four on C. townsendii. Macronyss

Abstract:

The original model of metal production was realized in the steppe of North Eurasia since 4th to 2nd millenium BC. It was characterized by unique features of the natural-climatic, territorial, economic-cultural (cattle-breeding) production system. Also, it was notable for specifics of ore preparation for melting using the pyrotechnic method (beneficiating and fining fire under temperatures to 1 000°C), and the chemical approach (oxidation by potash), recovery of cooper in reverberatory furnaces with segregation of smelted metals on the pyroxene or olivine slag box above and the whole pancake-sh

Through an analysis of three interpreted mines in northeastern Minnesota, this article illuminates how the region’s public history is complicit in the ongoing process of settler colonialism.

In 2016, a Mathematics-in-Industry Study Group (MISG) project considered the construction of mining sequences, that is, the process connecting ore extraction with specific orders. In particular, the meeting considered the potential for using knowledge about geological variability within the ore. This article revisits this MISG project and the approach developed for thinking about the problem as the build for an order progresses. We provide new perspectives on this approach and outline possible ways for further development. References L. Caccetta and S. P. Hill. An application of branch and cut

Abstract:

With the demand for green mining in coal mines, filling mining is becoming more and more popular, resulting in more complex production systems and more potential safety hazards. Therefore, it is very important to evaluate the safety of filling mining mines and propose improvement measures. Aiming at the safety evaluation method of filling mining mines, this paper innovatively proposes a safety evaluation method based on entropy weight–attribute mathematical theory, which enriches the theoretical research related to the safety evaluation model of filling mining mines.

Abstract:

A large number of mines have been closed due to resource depletion, failure to meet safety production requirements, and other reasons. To effectively ensure the safety of the ecological environment above these closed mines along with the safety of engineering construction, it is necessary to monitor the secondary deformation of closed mines. Based on TerraSAR-X, Sentinel-1A data, and InSAR technology, this study obtained high-density secondary surface deformation data on the Jiahe Coal Mine and Pangzhuang Coal Mine in the western Xuzhou area. Combining mining geological data, we analyzed the s

Abstract:

Mineral demand rapidly increases; as a result, underground mining activities gradually dig into the earth’s crust to deeper levels. For instance, the depth of coal mines has reached 1500 m, whereas the depth of mines for nonferrous metals has already achieved around 4500 m. Deep mining faces a number of technical and environmental challenges, first of all, great rock mass stresses, high temperature and long winding distance. The traditional technologies are hardly capable to provide the development and extraction efficiency and safety. That is why the need in developing and implementation of n

There are around 493 coal mines in India (300+ underground and around190 opencast mines) engaged in coal production for meeting energy and other requirements of our country. Coal and the process of mining itself creates an environment conducive for self-oxidation leading to build up of heat and subsequently break out of fire. This causes safety hazards, decrease in production, increased in de-settlement of colonies, fire related fatalities and risk to life and property. Occurrence of fires in coal mines has always been an undesirable proposition for the coal mining community worldwide due to i

AbstractThe present article shows that, according to archaeological and literary evidence, an expansion in mining occurred in the early Islamic world as a result of changes in mining technology at the end of Late Antiquity. The production of gold, silver, copper, iron, and other minerals is shown to have peaked in the eighth and ninth centuries and then to have declined during the tenth and eleventh centuries due to insecurity and/or exhaustion of the mines. Mining development was financed privately, and mines were usually private property.

Long-term continuous monitoring of the mining activities in open-pit coal mines is conducive to planning and management of the mining operations. Additionally, this faciliatates assessment on their environmental impact and supervises illegal mining behaviors. Interferometric Synthetic Aperture Radar (InSAR) technology can be effectively applied in the monitoring of open-pit mines where vegetation is sparse and land cover is dominated by bare rock. The main objective of this study is to monitor the mining activities of four open-pit coal mines in the Wucaiwan mining area in China from 2018 to 2

Mines have a significant impact on the environment in Morocco, both ecologically and socially. Mining as a source of income and economic development also has crucial consequences. In environmental terms. The opening of mines often leads to the destruction of local ecosystems. From this, deforestation, biodiversity loss and habitat fragmentation are frequent consequences of mining.
