Canadian development expenses(CDEs) are the costs incurred for sinking or excavating a mine shaft, main haulage way or similar underground work after a mine comes into production[;] developing a mine before production[;] buying a Canadian mineral property. CDEs can be deducted at a 30% declining balance.

Les frais d'aménagement au Canada (FAC) sont les frais engagés pour le fonçage ou l'excavation d'un puits de mine, d'une voie de transport principale ou d'un ouvrage souterrain similaire après l'entrée en production d'une mine; le développement d'une mine avant sa mise en production; l'achat d'un gisement minier au Canada. Les FAC peuvent être déduits à 30 % de la valeur résiduelle.

Record 2 2012-05-02

English

Subject field(s)
  • Extraction Procedures - Various (Mining)
DEF

[A mining method in which] the ore is excavated in open stopes, retreating from one end of the stope toward the other. The orebody is developed first by a series of sublevel drifts above the main haulage level. The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for entrance to them and the stope face at the other end. Chute raises connect the haulage level to the lowest sublevel, at which the tops of the chute raises are belled out to form mill holes. Beginning at the starting raise the ore is benched down from the sublevels; the broken ore falls into the mill holes, where it is drawn off through the chutes. The stope face is kept nearly vertical as it is benched backward toward the passageway raise.

CONT

Wide-vein deposits contained within competent waste rock and at vertical or steeply angled inclination permit use of a method called sublevel stoping. This method can be likened to the month on the page of a calendar, with the top and bottom edges representing the main haulage levels where all of the ore from above is removed. Each row of weeks on the calendar page represents sublevels started from the right-hand edge raise toward the left-hand edge raise widened to full-vein width. The sublevels starting at the bottom left day of the calendar page are drilled with long holes in a circle around the opening, then blasted in one large blast, removing a segment of rock... along the sublevel. It would be like removing one day of the week from left to right, bottom to top of the calendar page, and dropping it to the bottom edge, where previously installed chutes funnel them to the train or load-haul-dump unit for haulage to the shaft.

French

Domaine(s)
  • Procédés d'extraction divers (Exploit. minière)
DEF

Variété de la méthode d'abattage par sous-niveaux où l'exploitation progresse de bas en haut. Dans cette méthode, le minerai peut être soutiré à la base de l'étage.

CONT

Les exploitations par traçage et soutirage [...] se développent considérablement: la chambre est un parallélépipède dont la section horizontale est à peu près un rectangle et dont la troisième arête est verticale ou à forte pente; des galeries horizontales permettent de forer dans la masse des trous de mines en éventail dans les plans parallèles; les mines situées dans un même plan sont tirées simultanément [...]. Le minerai tombe au fond de la chambre, où il est soutiré par des entonnoirs creusés dans la roche, en tête de cheminées descendantes qui aboutissent dans des galeries de ramassage et de transport.

Record 3 1999-10-21

English

Subject field(s)
  • Ore Extraction and Transport
DEF

The transportation of coal or mineral from the working face to the shaft bottom.

CONT

Underground haulage. The ore recovered in stopes spread along an orebody is transported to an ore dump located close the hoisting shaft. Special haulage levels are prepared for longer lateral transfer; they commonly feature rail track installations with trains for ore transport.

OBS

Haulage usually implies trams, tubs, or mine cars drawn by horses, locomotives or ropes, and electric or compressed-air haulage engines. Conveyors are not generally regarded as a haulage method.

French

Domaine(s)
  • Extraction et transport du minerai
OBS

roulage : Tout type de transport du minerai entre la sortie du chantier et l'ouvrage d'extraction.

Record 4 1996-05-31

English

Subject field(s)
  • Waste Management
  • Nuclear Waste Materials
  • Underground Mining
CONT

For both caverns and tunnels, excavation is from the central tunnel ways using conventional mining techniques. In the tunnel concept..., the prepackaged wastes are lowered down the shaft and brought to the emplacement vaults by rail. The packages are then unloaded by forklifts or other conventional container handling equipment and emplaced for permanent disposal. The cavern concept implements a secondary haulage system where packaged wastes are transferred from rail to the emplacement vaults by overhead crane.

CONT

The Konrad mine has some geological features which make it very suitable for disposal of certain types of radioactive waste. ... Geotechnical properties of the rock allow construction of disposal caverns of adequate volume. Galleries containing wastes in drums or contaminated components can be backfilled and sealed, as well as the rest of the mine, including the two shafts.

CONT

The concept [burying the waste deep underground in the Canadian Shield] isolates used fuel from the environment using a series of natural as well as manmade barriers. Used nuclear fuel bundles would be contained in vaults 500 to 1,000 metres below ground. These vaults would consist of a network of tunnels and disposal rooms about 2 kilometres by 2 kilometres that could hold 191,000 tonnes of used fuel.

PHR

To backfill, to seal galleries.

Domaine(s)
  • Gestion des déchets
  • Déchets nucléaires
  • Exploitation minière souterraine
CONT

La roche hôte doit posséder des propriétés mécaniques favorables à la réalisation des ouvrages de stockage et à la sécurité de leur exploitation pendant des dizaines d'années. La connaissance des caractéristiques mécaniques est nécessaire pour déterminer les dimensions et géométries optimales des ouvrages profonds (galeries, puits, cavités, forme de piliers...). Elles permettront de programmer la conduite des chantiers miniers. Les propriétés mécaniques de la roche hôte devront garantir la stabilité des différentes structures dans un domaine de profondeur pouvant aller jusqu'à environ 1000 m.

CONT

Les volumes à excaver pour créer un stockage en profondeur comprennent : les ouvrages de stockage proprement dits, puits verticaux pour les déchets de haute activité ou galeries horizontales pour les déchets alpha et les ouvrages d'accès, puits verticaux partant de la surface et galeries reliant ces puits aux ouvrages de stockage.

CONT

[...] le concept prévoit l'enfouissement des déchets dans des formations profondes du bouclier canadien. Le combustible irradié serait isolé de l'environnement grâce à une série de barrières naturelles et artificielles. Les grappes de combustible irradié seraient placées dans des enceintes, creusées à une profondeur allant de 500 à 1 000 mètres. Ces enceintes seraient formées d'un réseau de galeries et de chambres de stockage occupant une superficie d'environ deux kilomètres sur deux, pouvant contenir 191 000 tonnes de combustible irradié.

CONT

[...] les terrains doivent être suffisamment stables pour permettre la construction et l'exploitation des ouvrages souterrains (puits, galeries, cavités).

PHR

Remblayer, sceller une galerie.
