Slime Spawning

Hi, I have an issue about slime spawning rates  while in caves. While in caves to many slime spawn, I believe that this is due to the size of caves and the way that slime spawning works. No Matter how much light and torches I place down, slime will just keep spawning. The amount of slime spawning makes it unbearable to go mining for me. Please fix this and thank you for reading this far.
