摘 要:为了解决干河煤矿2-3021掘进工作面稳定性问题,自主研制了卷帘装置,用于临时支护,预防迎头掌子面、两帮矸石及围岩破碎影响施工。在巷道临时支护的前提下,采用锚杆和锚索联合进行永久支护,工程应用效果良好,围岩变形均在合理范围内,确保了掘进工作的安全进行。In order to solve the stability problem of the 2-3021 excavation face in Ganhe Coal Mine,a rolling shutter device was independently developed for temporary support to prevent the impact of head-on face,two sides of gangue,and surrounding rock fragmentation on construction.Under the premise of temporary support in the tunnel,anchor rods and cables were used for joint permanent support,and the engineering application effect was good.The deformation of the surrounding rock was within a reasonable range,ensuring the safe progress of excavation work.
