In comparison with all the other techniques, phytoremediation is the most ecofriendly and costeffective technique According to Prasad,it costs as little as 5%
The mining industry is at a tipping point where sustainability and decarbonization are top items on CEOs’ agendas To achieve a 15°C climatechange target by 2050, the mining industry will
The watercontrolled coal mining framework in ecologically fragile mining areas has three components: identifying the bearing capacity of the mining area’s
Abstract The mining industry is globally criticized for generating large amount of solid wastes often with a potential environmental impact This study presents a
The simultaneous use of the ecofriendly mining operations and the green mining strategy for the concentration and processing plant through Scenario 4 indicates the greatest impact on
Williams (2022) illustrated (using hypothetical scenarios with costs collected from international literature) that coal mining projects should be assessed on an
Adopting costeffective technologies and undertaking research and development to find new solutions will embed the industry in the circular economy This

Among the different activator concentrations tested, aggregate (M4) displayed superior singleparticle crushing strength (390 MPa) and better carbonization resistance It also used a lower concentration of NaOH, which enabled more costeffective and ecofriendly production
In recent years, with the exhaustion of coal resources in the central and eastern parts of China, the focus of coal mining has gradually shifted west (Bai et al 2019; Ju and Xu 2013; Li et al 2020; Yang et al 2014; Zeng et al 2018)In 2020, the coal output in western China was estimated to be 23 billion tons, accounting for 592% of the
Solidwaste coal gangue (CG) mixed with cement as underground backfilling material is widely applied in coal mines throughout China However, this material can pollute the environment during its production, preparation, and transportation, which is mainly caused by cement As a cementfree ecofrien
Earlier Conventional system of mining which includes drilling, blasting and crushing were employed for extraction of coal in opencast mines All these operations are resulting a lot of adversative
The cement's main ingredient is fly ash, a byproduct of coalfired power stations The mix incorporates 80 to 90 per cent of recycled products and reduces carbon emissions by up to 80 per cent
However, coal mine activity is criticized for its harmful environmental impact and especially for the large amount of wastes produced during the coal mining and processing For example, in China, the world’s largest consumer of coal, 45 billion tons of wastes are stockpiled in hundreds of dumps (Fan et al, 2014)

CDE Combo Offers Ecofriendly Sand Washing Techniques This has reduced the water requirement to such a level that the washing plants have become costeffective and sustainable even in areas reporting severe water shortages Increase in mining activities (coal, iron ore, metal, and minerals)
Surface Miner An Ecofriendly way of mining Conventional coal mining involves the process like drilling, blasting using explosives, excavating coal from giant excavators Surface miner eliminates all of the above process and adding cherry on top it leaves crushed coal of size 100 mm eliminating the need of crushing thereby saving
agement will minimize the impacts of coal mining on the environment and will help in preserving ecodiversity (Sheoran et al, 2010) Most of the conventional technology are either extremely costly or entails isolation of the waste sites (Sheoran et al, 2008a, b) New cost effective and environment friendly strategies are needed to re

Safe coal mining under the condition of protecting ecoenvironment is more necessary [1–9] Taiyuan, China, is one of the most resourceconsuming coal cities, facing serious ecoenvironmental issues [10–19] How to find sustainable and ecoenvironmental coal mining methodology is the challenge
The annual coal production from opencast coal mines in India was about 328 MT and overburden waste material of 53508 Mm 3 [4] The current annual production of coal ash is estimated around 600
Ecofriendly and costeffective strategies for metals recovery from printed circuit boards mining of a ton of precious metals (Au, Pd or Pt) leads to an environmental footprint between 10k and 17k tons of CO 2 [17] Crushing and sorting treatments have a much lower cost compared to hydrometallurgical processes
During 2019, Greenhouse Gases (GHG) emissions from the copper mining industry were recorded for a total of 16,366 thousand tons of CO2 equivalent distributed in 6,252 thousand by direct GHG (382% of total emissions from copper mining) and 10,114 thousand by indirect GHG (618% of the total)
CG is a residue produced from the processing of coal mining and coal washing It has been estimated that CG accounts for about 10–15% of raw coal production (Qureshi et al, 2020) A large amount of CG was piled in wastelands over the last decades due to the rapid growth of the mining industry in China
