Design of mine roof bolting systems
Method for scientifically determining best roof bolting pattern involves average bed thickness of mine roof, length of roof bolts, bolt tension and anchorage capacity, number of bolts per set across entry or room, spacing of sets along entry or room, width of roof span, and reinforcement factor percent decrease in roof strata bending; roof bolting design chart.
