Construction workers use ventilation devices to remove the smoke and dust generated by blasting; S7: Risk elimination: construction personnel conduct risk elimination on the tunnels created by blasting; S8: Slag removal, using a slag scraper to clean up the gravel in the tunnel; S9: Enter the next cycle.
