摘　　要：针对断层带、丢煤区逆向交岔点施工的现场实际,考虑采面回采因素,创新性提出锚网支护→锁口棚及抬棚→锚网支护→联锁锚索、护腿锚杆→补套抬棚的协同支护方法,效果良好。According to the construction in fault and reverse intersection of throwing coal zone,based on the analysis of mining factors,the collaborative supporting method was innovatively presented as follows：step 1,bolting with wire mesh;step 2,locking shelf and carrying shelf;step 3,bolting with wire mesh;step 4,anchor chain,leggings anchor support;step 5,making up sets of lift shed.Results showed that the method had achieved good results in engineering.
