Pillar And Stall Mining Of Coal

Collapse processes in abandoned pillar and stall coal ...

2020-11-1  While the methods of coal extraction varied through time (e.g. bell pits, shortwall, longwall), the pillar and stall method was widely used in the UK between the middle of the 14th and early 20th century (Fig. 1, Table 1) (Bruyn and Bell, 1999).Using this method coal was extracted from ‘stalls’, or ‘rooms’, supported by pit-props (Daunton, 1981), stacks and pillars

Definition of pillar-and-stall

See Also: pillar-and-breast, post-and-stall ii. One of the earliest methods of working coal seams in Great Britain. It is employed in thick seams and where valuable surface buildings require protection from damage by subsidence. A number of narrow roadways are driven in the coal seam to a predetermined boundary.

Introduction to Shortwall Mining - OneMine

GENERAL DESCRIPTION Shortwall mining is one of the newest mining meth¬ods to be introduced into the world coal industry. The technique of shortwalling seems to have a number of origins, but it is generally agreed that it is an outgrowth of pillar-and-stall mining where timbering was employed as the primary means of roof support.
