To combine like terms in the expression $$ 3b + 4 + 10 + 6b - 2 $$, follow these steps:

1. **Identify Like Terms:**
   - **Terms with $$ b $$:** $$ 3b $$ and $$ 6b $$
   - **Constant Terms:** $$ 4 $$, $$ 10 $$, and $$ -2 $$

2. **Combine the $$ b $$ Terms:**
   $$
   3b + 6b = 9b
   $$

3. **Combine the Constant Terms:**
   $$
   4 + 10 - 2 = 12
   $$

4. **Rewrite the Expression:**
   $$
   3b + 4 + 10 + 6b - 2 = 9b + 12
   $$

So, the combined expression is:

$$
3b + 4 + 10 + 6b - 2 = \boxed{9}b + \boxed{12}
$$
The combined expression is $$ 9b + 12 $$.
