Ground control

Recently , several mines in Australia, Finland and Canada have used a “Mandolin” bolting techniques. Cable bolts are placed parallel to a hanging wall in an open stope operation . These cables provide flexible yielding supports . They can withstand high deformation and yet prevent slabbing, which is the major cause of dilution .
Researchers at the University of Utah have developed an “equivalent elastic modulus” approach to modeling cable bolts with finite elements . The modeling techniques can include the effects of jointing without the need for a prohibitive number of specialized elements.

Заранее спасибо

Что-то вроде "слишком большое количество специализированных элементов" (т.е. так много, что нам и не сделать как нужно)
