Bezpieczeństwo prowadzenia prac górniczych na pełnym morzu
(Wydawnictwa AGH, 2011) Hajduk, Jerzy
To conduct mining activities on the high seas requires the introduction of new technological solutions. In addition to the use of new technologies for mining, ship's positioning and resolve issues more locations, handling supplies and mined material, a matter of the system is to ensure an acceptable level of safety for all components of a technological process of such a venture. The article provides safety requirements, which should be implemented by the participants engaged in the mining of natural resources of the seabed, and additional considerations arising from the pursuit of a new type of human activities at sea.

Surowce mineralne z dna mórz i oceanów - stan rozpoznania i perspektywy
(Wydawnictwa AGH, 2011) Szamałek, Krzysztof; Mizerski, Włodzimierz
Seabed minerals constitute a possible new source for mineral commodities. Marine mineral resources occur in the bedrocks beneath the ocean floor, the ocean floor itself, in the sea water and in the shallow, coastal zones. The perspective of their extraction is shaped by the following factors: geological, legal, technical, technological, environmental and economical. It appears that in spite of years of on-going research, mineral resources of seas and oceans are still known insufficiently. This applies in particular to polymetallic massive sulphides ores, Co-crusts, metalliferous clays or methane gas hydrates. The deposits of crude oil and gas in seas and oceans are still poorly known in the deeper parts of the oceans. Mineral researches of oceans are conducted by several countries (e.g., Russia, US, France, Japan, Germany, South Korea, China, Poland); their activity is regulated and controlled by the International Seabed Authority. The perspective of marine minerals extraction is more imminent in rich, technological advanced countries; having access to the sea in itself is a factor of lesser importance. Underwater geological surveys are costly and can be undertaken only by countries which are characterized by either a strong economy and/or willingness to conduct an active concession policy and close cooperation in managing of measured mineral reserves.
