Mining is very important, as ore pretty much fuels the game. If there was no mining, then there would be a much less diverse variety of weapons and armour available, making the game pretty dull.
That's why it's important to get your mining skill up.
From level 1-20 you should mine copper from the south varrock mineFrom level 20-40 you should mine iron from the mine near rimmington or varrock
When you reach level 40, it should be much easier to mine coal. You can mine coal at level 30, but it will take much longer, besides, if you level up with the other ores, you can either make money by selling them or you can keep them and maybe use them later (I recommend this method, it's more profitable).
I also recommed that you buy and adamantite (Or adamantine I always forget how you spell that) or rune pick axe.
A good place for paid runescape members to mine coal, is at the mine near ardougne, which also has a bank fairly close by, this will speed up your mining and make you more efficient.
If you're a free runescape member, you can mine coal in the dwarven mines, however there isn't a bank nearby, so you wont be very efficient.
Now, mine coal until you're level 60
Since you're level 60 you can go to to mining guild to mine coal until you're level 85
And now that you're mining level 85, you should go and mine rune in the wilderness or from the heroes guild (Much safer). Rune seller for between 10,000-15,000 per piece, so I think you'll agree that it's certainly worth the effort to do it.
When following the steps above, I strongly suggest that you keep all of the ore you get and smith it into something useful. Otherwise, feel free to sell it and see some immediate return for your efforts
