The researchers studied how to choose roof bolting for a coal mine with close-distance seams. They used theory, tests, and simulations to find the best spacing for the bolts. The maximum depth of floor failure was calculated to be around 3.2-3.3 meters. With an anchorage length of less than 2.4 meters, the minimum seam spacing needed for roof bolting was determined to be 5.6-5.7 meters. Pull-out tests showed that a spacing of at least 6 meters is needed for strong bolt support. This information can help design roof bolting for similar coal seam conditions.
