Turkish Thoracic Journal/Türk Toraks Dergisi, 2015 The underground coal mining, in terms of fatal and injury accidents, has the first place among all businesses due to "spontaneous combustion of coal" and "presence of methane gas" in coalmines. In May 2014, the most casualties (301 people) of recent years occurred in the Soma Eynez mining quarry that accounts for almost half of the death of the last 30

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022 We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Electrodialysis of coal mine water
Water Resources and Industry, 2021 The treatment of model solution resembling the coal mine water from the “Bolesław Śmiały” coal mine in Łaziska Górne, Poland, was investigated. Two cases were investigated: 1) electrodialysis is directly applied in concentration of coal mine water; 2) coal mine water is pre-concentrated in the NF-RO system and then fed to the electrodialysis.

Coal rock image recognition method based on improved CLBP and receptive field theory
Deep Underground Science and Engineering, Volume 1, Issue 2, Page 165-173, December 2022., 2022 In view of the evident differences between coal and rock in visual attributes such as color, gloss, and texture, the complete local binary pattern (CLBP) image feature descriptor is introduced for coal and rock image recognition, and the original algorithm oversimplifies local texture features by ignoring imaging information from higher‐order pixels ...
