The dust falling indicates a cave-in tile nearby. The entire underground is effectively a giant game of minesweeper.
If you know how to play minesweeper, you can mine without supports.
If you don't know how to play minesweeper, you always need a support.
The best way to get l1 ores is to find a cave, and prospect aboveground above the cave system to find ores, mark where they are and then mine to that spot in the cave below you (the overwold and the cave layer match up perfectly)
Otherwise you can also mine everywhere in the caves to see the stone types, do a tunnel mine to try and find things if you know how to mine without supports or any other trick you want. There's not really a 'true' best way.
