矿山酸性废水处理与模拟的清洁技术 //www.a-i-l-s-a.com/volIssuenoIssue/clean-technology-for-the-treatment-and-modelling-of-acid-mine-drainage-effluent/ 29-06-2020 2020-07-04 Padmaja Megham 2019-20年特刊1期-可持续矿业

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&lt;4) an...

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...

采矿是一种危险的活动,由人类产生,为他们的期望提供必不可少的质量和安全的日常舒适。有关地区的采矿提供了砾石、破碎机和石块等原料,用于发展道路、铁路和其他基础设施。从最近几年开始,开采率已经增长了几倍。它带来了植被和动物群生物多样性的丧失和有关地区的地貌变化。房颤< / p >

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...

微塑料是广泛分布在印度海洋和淡水中的主要污染物,对生物构成重大威胁。世界经济论坛的估计,到2050年,世界海洋中所含的塑料重量将超过鱼类。塑料的极端生产和使用将导致塑料垃圾的处理,塑料降解为微塑料。微塑料数量的增长将继续增加微塑料

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&rsquo;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&ndash;70% of the world&am...

增加粮食产量和提高周围环境质量的必要性导致了寻找材料来控制或调节水和风蚀。如今,覆盖已成为农业生产中一项必不可少的决定性措施。减少除草剂和各种化肥的施用,控制杂草生长,保持土壤水分和土壤温度。本文详细回顾了不同的研究
加纳大规模采矿的农民教育和风险认知 //www.a-i-l-s-a.com/volIssuenoIssue/farmers-education-and-risk-perceptions-of-large-scale-mining-in-ghana/ 18-06-2020 2020-07-04 弗雷德Owusu-Ansah 2019-20年特刊1期-可持续矿业

Introduction The importance of research on communities&rsquo; risk perceptions has been expressed.1, 2, 3 Studies on risk perception are sufficiently good predictors of communities&rsquo; 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...

在加纳,几乎没有使用家庭农民作为分析单位来考察教育对大型采矿项目风险认知的相对影响的实证研究。本研究结合文献证据、混合方法、皮尔逊卡方(X2)和相关分析。采用系统随机抽样方法对农户进行抽样。采用SPSS软件对725个家庭的数据进行分析。教育程度与家庭生活水平之间没有关系

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...

孔科拉铜矿四井是采用分段空场采矿法(sls)采矿的无轨地下矿山。4号竖井希望在未来5年内将矿石产量从每年100万吨提高到每年300万吨,但矿石回收率为70%或以下,贫化率为20%或以上。为了实现300万公吨的预期年度目标,矿石回收率应从70%增加到85%,稀释应减少

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&nbsp;Remote sensing and geographical information systems (GIS) are important tools for studying the distribution of lan...
