Question: Consider the cable bolting array shown in the sketch. Develop an expression based on a requirement for equilibrium in the direction normal to the vein

Consider the cable bolting array shown in the sketch. Develop an expression based on a requirement for equilibrium in the direction normal to the vein dip that brings into association vein dip ?, bolting angle (from the horizontal) ?, bolt spacing S (assume a square pattern), bolt tension T, and so forth. Note: specific weight of rock is ? and two bolts per hole are used.
