I tried to make the generation of through Hyde bedrock miner, but my ore is generated.

I'm pretty sure we need more information than that like code.

public class OreGeneration implements IWorldGenerator {

    private WorldGenerator TEST_ORE;

    public OreGeneration() {
        TEST_ORE = new WorldGenMinable(ModBlocks.TEST_ORE.getDefaultState(), ;
    }

    @Override
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunkProvider) {
        switch (world.provider.getDimension()) {
            case 0: //Overworld
                runGeneration(TEST_ORE, world, random, chunkX, chunkZ, 20, 0, 64);
                break;
            case -1: //Nether

                break;
            case 1: //End

                break;
        }
    }

    private void runGeneration(WorldGenerator generator, World world, Random rand, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight) {
        if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight)
            throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");

        int heightDiff = maxHeight - minHeight + 1;
        for (int i = 0; i < chancesToSpawn; i ++) {
            int x = chunk_X * 16 + rand.nextInt(16);
            int y = minHeight + rand.nextInt(heightDiff);
            int z = chunk_Z * 16 + rand.nextInt(16);
            generator.generate(world, rand, new BlockPos(x, y, z));
        }
    }
}

public class CommonProxy {

    public void init() {
        GameRegistry.registerWorldGenerator(new OreGeneration(), 0);
    }
}

I tried to make the generation of through Hyde bedrock miner, but my ore is generated.

Now what is the problem?

Mine ore is not generated in the world.
