Usage of computer X-ray microtomography method for core analyses from deposits with scavenger reserves

1 Sep 2020 / by PONOMAREV ANDREY ALEXANDROVICH, KOBYLINSKY DANIL ALEXANDROVICH, ZAVATSKY MIKHAIL DMITRIEVICH

Abstract: In order to identify the productive and perspective perforation in the deposits with scavenger reserves, one often faces a number of problems that prevent the selection of the most perspective intervals. One can add to these intervals the misinterpretation of geophysical well logging, as a result of drill mud colmatation into the formation or …

Receptor modelling of air pollutants for source apportionment on coal-based anthropogenic activities

1 Sep 2020 / by AISHWARYA MISHRA, SANJAY KUMAR PALEI, NETAI CHANDRA KARMAKAR

Abstract: Identification of sources of air pollutants plays a predominant role in coal-based anthropogenic activities to manage the air quality. Coal mining and thermal power plants (TPPs) are two multi-activity-centred coal-based sources that affect the ambient air quality of the region. Among five air pollutants under consideration, the annual average concentration of PM10 and PM2.5 …

Controlled Blasting Practices in Quarries for Sustainability: a case study

1 Aug 2020 / by P. BALAMADESWARAN, A. K. MISHRA

Abstract: In the mining industry, the rock breakage by drilling and blasting plays a vital role as it facilitates not only fragmentation of rock mass but also controls consequent mining operation. In order to increase the production capacity or prolong the life of the deposit, the expansion of mine is unavoidable. However, when the mines …

Whole body vibration exposure and its effects on heavy earthmoving machinery (HEMM) operators of opencast mines – a review

1 Jul 2020 / by ANAND S. SHARMA, S. K. MANDAL, G. SURESH, S. ORAON, D. KUMBHAKAR

Abstract : Operators of opencast heavy earthmoving machinery (HEMM), during their 8-hour shift duration, are regularly succumbed to the high level of whole body vibration (WBV) amplitudes. Due to long and continuous working in the field, the operators of HEMM may yield to adverse health effects and results in hazardous conditions if the magnitudes repeatedly …
