摘要：
Based on the "two-hard" condition in the thick coal seam, a now technology on roof control is applied to decrease the weighting degree in Xinzhouyao Mine in this paper by the method of blasting roof. Meantime, the relation between the support and surrounding rocks is studied, and the support structure and properties is discussed to be suitable for the "two-hard" condition.
