Ascent by stoping is less feasible with incremental emplacement because if the active magma body is below the top of a pluton, stoping rearranges material within the pluton and produces no overall ascent.

Given the size of the blocks sinking, there should be abundant small fragments produced by natural fragmentation, however there is a paucity of small fragments at pluton margins and this is inconsistent with stoping.

Evidence for a stoping mechanism has been described locally from the margin of the Tregonning intrusion, where a series of intrusive sheets extend out from the roof zone of the intrusion into the country-rock.

Moreover, there were several fine plays in the field, including a back-to-the-wall catch by Cleveland center fielder Marquis Grissom, and a rally-stoping play by acrobatic Tribe shortstop Omar Vizquel.

Upon entering sandstone wall-rocks the fault became mineralized and some stoping was seen to surface ( 20m ) near the end of the drive which extended but was inaccessible but almost certainly extends below two surface shaft collapse located above.

Stoping is considered " productive work ", and is contrasted with " deadwork ", the work required merely to access the mineral deposit, such as sinking shafts and winzes, carving adits, tunnels, and levels, and establishing ventilation and transportation.

Vertical crater retreat ( VCR ), both caving and post-fill, have been the predominant mining method utilised within the Nkana mine, but is now being converted to a combination of sub-level caving ( SLC ) and open stoping techniques.

Indeed, the rich 1885 assay influenced wanton expenditure on an elaborate treatment plant costing ?1, 500, even though by 1888, when the mine's treatment works were completed, the amount of driving and stoping after the shaft had cut the lode, was minimal and only 2, 000 tons had been stacked.

This is, in my opinion, a violation of WP : POINT . The purpose is to create this, get users who agree with 9 / 11 truth to post in it and smear Mongo, with the purpose of stoping him from doing his responsiblities as an admin .-- Jersey Devil 04 : 39, 1 June 2006 ( UTC)
