Design of bolting systems to reinforce bedded mine roof
Method for designing systems of vertical bolts to reinforce horizontally bedded mine roof, developed from model tests; general equation for roof bending strain; basic roof bolting design formulas derived and their implications considered; chart and procedure to determine bolt spacing, tension, and length that will provide desired safety factor increase.
