| Abstract: | In mining thin seam with room-and-pillar method using continuous miner,roadways in rectangular cross-section are often excavated,and the ratio of widthover height of the roadways is greater than 4.Roof-bolting is used as permanentsupport in such roadways due to its low height and large span.The mechanicalproperty and behaviour of roof is of special character.The paper discusses the roofmechanical character of the wide roadway and analyzes the mechanism of roofbolting based on ground pressure measurement in site.Ideas and suggestions areput forward for determining the main parameters of roof control. |
