32、根据掘进情况，对盾构设备及输送管路及时进行清理。在掘进过程中加强地面沉降监测。号站在采空区附近，后期施工可能会遭受采空地面塌陷地质灾害危险.。在施工过程中加强对开挖面的监测，发现空采区及时处理。文档编码:CN1L3A6L3S10 HB6K8J6E8K7 ZL8T5X6S10I3文档编码:CN1L3A6L3S10 HB6K8J6E8K7 ZL8T5X6S10I3文档编码:CN1L3A6L3S10 HB6K8J6E8K7 ZL8T5X6S10I3文档编码:CN1L3A6L3S10 HB6K8J6E8K7 ZL8T5X6S10I3文档编码:CN1L3A6L3S10 HB6K8J6E8K7 ZL8T5
