Global production and consumption of plastics have continued to rise and the problem is that most of us use and then toss way more plastic than we need. Plastic treating is the pillar of the economy in most of the advanced economies and several plastics machinery manufacturing units in India are plus and their consumption in the year 14-15 about 14 MMT.1 Plastics industry produces and exports a wide r

The growing amount of microplastics will continue to increase microplasti

Agriculture sector consumes the highest quantity of water in the world around 70% of total usage (Qin et al., 2018). In which, 80% of global cropland is covered by non-irrigated (rain-fed) that contributes 60–70% of the world&am

Mulching has become now a days an essential and decisive exercise in agricultural production. It lessens the application of herbicides and various chemical fertilizers, control the weeds and maintains the soil moisture and soil temperature.

Sublevel open stoping method popularity has grown since 1970 and at the end of the 20th century (Henning, 2007). (Jang, 2014) cited (Austrade, 2013) reported that 70% of underground mines in Australia use sublevel open stoping mining method. Pakalnis et al., 1996 found that 51% of underground mines in Canada use sublevel open stoping method. This mining method is applicable to large

..]]> Konkola Copper Mine’s Number 4 Shaft is a trackless underground mine applying sublevel open stoping (SLOS) mining method. Number 4 shaft wants to increase ore production from 1 million metric tonnes per annum to 3 million metric tonnes per annum in the next 5 years but ore recovery is 70% or less and dilution is 20% or more. In order to achieve the desired annual target of 3 million metric tonnes ore recovery should be increased from70% to (≥85%) and dilution should be reduced f

This study combined evidence from literature, mixed methods, Pearson’s Chi square (X2) and correlation analyses. Systematic random sampling was used in selecting farmers. Data obtained from 725 households was analyzed using SPSS. The hypothesis “education has no relationship with farme

It is the key information for resource management and policy development, as well as for other allied issues. In-depth knowledge of land use and land cover features represents the basics for land classification and management.1 Remote sensing and geographical information systems (GIS) are important tools for studying the distribution of lan

..]]> Opencast coal mining has an immense impact on the changing land use and land cover pattern of any colliery belt. This is the main thrust of the present study. Land-use practices, like built-up area, cropland, vegetation, water body, bare land, mining area etc. have been identified. The pattern of changing land use and land cover in the Mangalpur private opencast colliery has been analysed. At the same time, entire Raniganj block has been studied with the help of secondary data.

The International Energy Agency in its 2019 report1 on coal information states that the coal production has increased from 3000 million tonnes (Mt) in 1971 to 7000Mt in 2019. The report provides that China ranks on the top position in terms of coal production (3,523 Mt) followed by India (716 Mt) and United States at third position (702.3 Mt). The environmental impact of coal industry has attracted a

The techniques involved in mining cause tremendous destruction to the environment and health of people living in nearby areas. There is a growing consensus on sustainable and efficient mineral development which will help in avoiding the clash between economic and environmental interests. Deployment of advanced and sustainable technological solutions in the en

The mining procedures, the materials are expelled from the earth by stabbing and detonating. The two methods of mining for desolation of nature ore are, opencast (surface mining) and underground mining. Opencast mining process is making for extracting minerals near the surface of the earth or for soft-rocks. The classification of these types of mining is based desired parameters f

..]]> The mining is a dangerous activity produced by humans for giving indispensable quality and security to their expectation for everyday comforts. The mining in the concerned zones gives crude materials as gravels, crusher and stones etc. for development of roads, railroad lines and other infrastructures. From the most recent couple of years the mining rate has expanded a few times. It brings about the loss of biodiversity of both vegetation and fauna and land form changes of the concerned zone. Af

Furthermore, the effluent from slag washing has high acidity (pH<4) an

..]]> Acid Mine Drainage (AMD) exists as a phenomenon that involves the release of acidic water and metal conjugates, in and around mines, degrading the surrounding water environment. A real-time mining effluent is treated using low-cost adsorption technology using Combined Vegetable Waste Carbon (CVWC) as sorbent. Batch sorption was reviewed to know the effect of process factors on the removal of Cadmium (Cd), Zinc (Zn), and Iron (Fe). A two-level CCD (Central Composite Design) with three factors was
