Dear Readers I am pleased to present before you this special issue of Current World Environment on Sustainable Mining. I thank all the contributors for their efforts to share their research on the topic with the global community. I also thank the reviewers for dedicating their time and suggestions which have considerably enhanced the quality of the manuscripts. I must appreciate the efforts of the editorial office of the journal which made the final compilation and the release of the issue po...
Introduction The economic development of any country mainly depends significantly on the mining industry.1 Majorly, the mining operations generate vast quantities of wastewater as the result of AMD.2, 3 The significant effect of the mining is the degradation of natural resources.4 The amount of water used in the mining industry is huge and generally higher than what is predicted due to the mining processes involved. Furthermore, the effluent from slag washing has high acidity (pH<4) an...
酸性矿山排水(Acid Mine Drainage, AMD)是矿山内部及周围酸性水和金属缀合物释放,使周围水环境恶化的一种现象。采用蔬菜废碳组合(CVWC)作为吸附剂,采用低成本吸附技术处理实时矿山废水。综述了间歇吸附法去除镉(Cd)、锌(Zn)和铁(Fe)的工艺因素。具有三因素的两级CCD (Central Composite Design)
Introduction Mining is extraction of valuable minerals or other geological materials in or on the earth planet. 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...
Introduction Microplastic pollution is a developing environmental problem in aquatic fields. 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...
Introduction Coal is mined for commercial purpose in more than 50 countries across the world. 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...
采矿业经常被贴上污染部门的标签,因为它涉及到以不可持续的方法进行的大规模资源开采。采矿技术对附近地区的环境和居民的健康造成了巨大的破坏。人们对可持续和高效的矿产开发越来越达成共识,这将有助于避免;nbsp;经济利益和环境利益之间的冲突。在欧洲部署先进和可持续的技术解决方案
Introduction It is becoming increasingly clear that the challenge of feeding tomorrow’s population is to an outsized extend about improving productivity of water within present land use, as new arable land is relatively limited (Prem et al., 2017). 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...
Introduction The importance of research on communities’ risk perceptions has been expressed.1, 2, 3 Studies on risk perception are sufficiently good predictors of communities’ attitudes and actions toward development projects.4 Such studies are also essential in determining whether or not there is potential for community conflict,5 and thus, help identify how mining companies and communities could co-exist and harness the resource endowment in the catchment area in a susta...
Introduction Sublevel open stoping (SLOS) is a self-supporting mining method which is widely used in the world. 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...
Introduction Proper understanding of land use and land cover is an important factor for several planning and management activities of any region. 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...
露天煤矿开采对任何煤矿带不断变化的土地利用和土地覆盖格局都有着巨大的影响。这是本研究的主旨。土地利用实践,如建成区、农田、植被、水体、裸地、矿区等已经确定。分析了曼加尔普尔露天煤矿土地利用与覆被变化规律。同时,利用二次资料对整个Raniganj区块进行了研究。SOI地形图
