A method and apparatus for observing and/or repairing damages on a wall of a coke oven or combustion chamber is disclosed. The damages on the wall are detected by positioning a heat resisting lance which includes an optical system for observing an image on the wall and conduit having a nozzle for spraying repairing materials onto damaged areas on the wall in the inside of the coke oven and moving the lance horizontally and vertically within the coke oven along its wall while observing the image on the wall at an outside of the coke oven through the optical system. When the damages are detected, the damages are repaired by spraying the repairing material onto the damaged area on the wall from the nozzle.
