(80) After analysing the "Project for the open-cast working of the Buseiro zone" dated July 1994, submitted as an Annex in the document from Uría Menéndez, the Commission noted that the Buseiro deposit shows numerous geological irregularities and therefore uncertainties in its future operation.

(38) As regards the open-cast mining sector of Buseiro, the report endorsed by independent experts confirms that until 1998 the deposit had been worked integrally, i.e. the overhead and wall veins of seam I. The movements of excavation residues and the mine waste tips produced until now correspond with the integral working of the said seam I.

As to the exceptional costs of closure, the company report does not provide an explanation of the exceptional costs resulting from the restructuring of González y Díez SA. On the contrary, it refers to expenditure of ESP 319896354 for the repayment of loans and subsidies not related to restructuring, expenditure of ESP 232589000 by way of investment in equipment for open-cast working, and expenditure of ESP 158973459 in investment for the modernisation of underground workings, none of which are related to the closure of the installations.

- "holding" means any establishment, construction or, in the case of an open-air farm, any place situated within the territory of the same Member State, in which animals covered by this Regulation are held, kept or handled,

Coal mining today is large-scale surface mining that employs a skilled workforce trained to operate and maintain a new generation of highly sophisticated mining equipment and processing facilities.

Alberta's oil reserves are sourced in the following ways: by strip mining shallow bitumen sands deposits, where 90% recovery of original oil-in-place is achieved; by in situ extraction of bitumen sands in deeper deposits using cyclic steam stimulation, now achieving recovery factors of 35% to 40%; by steam-assisted gravity drainage, typically achieving recovery factors exceeding 50%, and sometimes up to 70%; by in situ extraction of bitumen carbonate deposits, where two successful commercial-scale pilot projects in the Grosmont deposit are now both proceeding to full scale-development; and by multiple fracking of horizontal wells in tight oil shales containing a large oil resource little developed as yet, but classed as “proved undeveloped”, based o ...[+++]n success exploiting analogous tight oil shales in the U.S. These recent developments and improvements in recovery factors indicate Alberta's proved oil reserves are 848 billion barrels.
