To answer your last question, yes.
Here is a Russian ammo truck hitting a Ukrainian mine that was fired by Ukrainian artillery, into the Russian rear area near the Velyka Novosilka axis, likely very recent.

Russian remote mining vehicles operating in Donetsk recently, supposedly they were some of the last vehicles to leave Kherson.

The artillery-laid minefields are MUCH easier to clear than buried mines however. Their main purpose is delay, not destruction. They do work as "surprise" weapons when they are fired into areas that have already been cleared of conventional mines. Drivers who are not being real careful will hit them even on paved roads. Once you realize they are a threat, people become careful, see them, and stop. Of course, these mines can be much more difficult to see in off-road usage. Such mines are real useful against a fleeing enemy, because often troops that are fleeing aren't "careful". They also work well at delaying advancing troops because even if you see them, you have to clear them. If you have a bulldozer or something similar and are on a "good" road, it isn't too hard to do. At one point in history it was possible to clear these mines "by hand" pretty easily, because they were anti-vehicle and you could just pick them up. Today, the anti-vehicle mines have "anti-disturbance features" that makes that pretty hazardous :-).
