What reading level is Geology of Coal ; Examination of Coal Properties ; Drifts, Slopes, And Shafts ; Methods of Working book?
To quickly assess the difficulty of the text, read a short excerpt:
Where thicker beds of quicksand occur, it may be necessary to drive several series of piles, each successive series being driven inside the former after the material has been exca- vated to a point near the bottom of the first piles driven.
The second set of piles having been driven, the material Digitized by Google §39 DRIFTS, SLOPES. AND SHAFTS 59 within these is excavated to a point near the bottom of the piles, and, if necessary, a third set of piles is driven within the second. This method... is illustrated in Fig. 35.
After driving, the first set of piles a should be strength- ened by timber frames or timber sets at their top and half- way of their length, as the material is excavated from the space they enclose. It is important that these frames should be set promptly and braced by cross-buntons; they are sup- ported by punch blocks e. As will appear from the figure, it will be necessary to set the first sets of piles back a sufficient distance from the shaft to allow for the decreased size of the excavation when each series of piles is driven.
