There are 2 220 kV high voltage pylons erected in front of my house, one less than 20 meters away and one not 10 meters

It's definitely a hazard. And it's already more serious. Being that close, I'm guessing you should be able to hear it at night.

To move away as soon as possible, as for the state compensation, that is to see you live in the front or the pylons stood in the front, if the pylons are built after you live there, then you can ask the power department to do the appropriate compensation, if they do not agree, you can sue to the court, basically, will win the case. (However, I am wondering, according to the state regulations, when the tower was built, you should have been allowed to demolish it ah?)
