First, you need to find your NetherOres.cfg file in the config folder (...AppData\Roaming\.technic\tekkitlite\config is the location, by default), open it with Notepad, & scroll down to the "worldgen" section. There, it will say stuff like, I:oreCoalBlocksPerGroup=20, I:oreCoalGroupsPerChunk=8, I:oreCoalMaxY=128, I:oreCoalMinY=128, etc. The problem arises from all the ores having the MaxY & MinY both set to 128, making them all spawn in a very dense pattern, just below the bedrock ceiling @ Y=128. To fix this, simply replace all occurances of "MinY=128" with "MinY=1" (1 is what it should have been, according to the mod author). Replacing is easily done by hitting Ctrl+H, putting "MinY=128" in the 1st box, "MinY=1" in the 2nd, and hit "Replace all." Then all you need to do is save the changes, & (re)start the technic launcher. Do note that, any chunks that you have loaded in the nether before you change this will still have the ores all on the ceiling still, which can be kinda fun if you disabled the ores from exploding in the .cfg file (or if you didn't, & just want a huge chain-reaction =P).

Thank you so much. I did exatly what you said and it did the trick
