More information can be found on the internet and by carefully working through the key, link (here) you will have some success I'm sure. You can start with either the 'Mine-keys' or 'Plants' page but I suggest using both. You will not be able to identify everything, so don't try and start off with the easy ones.

Rearing miners through the winter.Some species cannot safely be identified from the mine alone. A look at the larva or pupa can help in some cases but this needs care.
If you find a mine containing a live larva or pupa; cut up some old tights and tie off one end, put the leaf inside and tie off the other end and secure it to a low growing bush in the garden. Don't forget a label! Choose a sheltered spot for this, you are trying to mimic what would happen to a leaf 'in the wild'. Bring the leaf indoors next year March or April time, remove the leaf from the tights, put it in a pot and wait to see what emerges. Phyllonorycter mines work well to start with.
Best of luck.
