Using the sharingan, Sasuke and Itachi are able to see chakra through cave walls in their fight with Kabuto. And Sasuke see's the chakra of landmines underground in his fight with Deidara.

If a enemy was covered by only a thin layer of smoke you would think sharingan / rinnegan would still be able to see the chakra of the enemy.
