摘　　要：本文针对小官庄铁矿东区高应力软破岩采准巷道变形控制存在的主要问题 ,提出了以喷锚网为主要支护手段的一次性强化综合治理技术 ,现场实施并取得了成功。该技术对有效控制高应力采准巷道的变形 ,实现无底柱采场的正常回采具有重要参考价值。Taking Xiaoguanling Iron Ore Mine as example,crucial issues about how to control the deformation of preparatory workings surrounded by soft and fractured rock under high stress are discussed.The fechnique of reinforced combined support using shotcrete and bolting wire mesh is introduced which has been tested in the site as successful,This support technique is worth an example to be taken by other mines where the conditions are similar like those of Xiaoguanling Iron Ore Mine.
