The Deepwater Horizon oil spill accident (variously referred to as the BP oil spill/disaster or the Macondo blowout) commenced on April 20th, 2010 on the BP-operated Macondo Prospect drilling platform. The ensuing fire aboard the drilling platform claimed eleven lives. Following the explosion and sinking of the fl oating oil rig, a sea-fl oor oil gusher fl owed for 87 days, until it was capped on July 15th, 2010. Th e total discharge has been estimated at 4.9 million barrels (780,000 m3), and the event was considered by some authorities to be the largest accidental marine oil spill in the history of the petroleum industry. 

On April 20, 2010, the Deepwater Horizon (DWH) platform drilling the Macondo well in Mississippi Canyon Block 252 exploded, killing 11 workers and injuring another 17. The DWH oil spill resulted in nearly 5 million barrels (approximately 200 million gallons) of crude oil spilling into the Gulf of Mexico (GoM). The full impacts of the spill on the GoM and the people who live and work there are unknown but expected to be considerable, and will be expressed over years to decades.

Water is among the most essential resources that sustain Earth’s ecosystems, but these systems are currently under threat due to land use and climate change. Assessing the impact of this global change on water security and ecosystem’s functions is not only the key concern of the United Nation’s Sustainable Development Goals, playing a key role in sustainable development of society, but also the most important research focus in “Future Earth” and Earth critical zone research.

В работе на основании обобщения опыта применения противофильтрационных завес в мировой практике в различных областях экономики и новых результатов исследований рассмотрены способы сооружения различных типов завес с целью создания благоприятных условий проведения горных и строительных работ, защиты застроенных территорий от подтопления и охраны водных ресурсов от истощения и загрязнения. Изложены технологии нарезки и заполнения траншей, инъектирования водоносных пород закрепляющими составами в различных геолого-гидрогеологических условиях.

В первом разделе приведены размеры загрязненных земель к началу ХХI века по каждому административному субъекту Российской Федерации. Оценивались площади территорий, подверженных хроническому техногенному загрязнению в сфере влияния городских поселений и магистральных дорог. Загрязненные земли занимают 4% российской территории (683 тыс. кв. км). По Федеральным округам этот показатель находится в интервале от 0,7% (Дальневосточный округ) до 19,3% (Центральный округ).

The objective of this chapter is to provide a foundation for the rest of the Handbook. It does so by initially describing the history and outlining the purpose, which is then followed by a definition of its structure or organization, which is immediately succeeded by a Reader’s Guide for each chapter. Finally, it alerts the wader to the current rush of events that make for a short shelf life for some of the presented information, especially laws in force and controlling political events. Nevertheless, this Handbook is designed to be more a manual stressing basic principles that change little, rather than a textbook supplier of details that are constantly in transition. As such, the Authors and Editors have tried to focus upon more universal design concepts in the field. Even if specific examples become dated, the Handbook is meant to be an enduring repository of basic engineering theories that form the foundation of environmental protection in the mining industry.  <...>

Mining operations can generate enormous amounts of waste (i.e. waste rock and tailings) that must be managed and handled in an appropriate way to avoid any possible negative environmental impact, such as air, soil and water pollution.

Геометаллургия – это междисциплинарный подход, играющий ключевую роль в оценке любого проекта или действующего предприятия. Он фокусируется на пространственной характеристике различных типов руд или доменов внутри месторождения, учитывая их влияние на обогащение, производительность добычи, а также экологические аспекты и аспекты рекультивации.
