Ahead is another rotating gear. This one has a flame trap on top. If you have any items that confer fire resistance, equip them now. When you jump across the gap onto the gear, 2 mummies with bows appear on the opposite ledge.

If you like, you can jump back onto the ledge where you started and shoot the enemies from there. It helps to use a weapon with good long-range capabilities, like the railgun, one of the rifles, or even the Staff.

Jump onto the gear and then grapple the golden ring on the wall above on the left. Jump toward the wall to avoid the flames.

Then swing to the left and jump onto the stairs. If you didn't destroy the mummies before, shoot them now at close range, taking care to avoid the flame vents ahead.

Shoot them at close range, taking care to avoid the flame vents ahead.

Then step on the pressure pad to deactivate the vents, as well as the flame trap on the gear you just passed.

If you're playing co-op, Lara or Carter should grapple swing across and step on the pressure pad to deactivate the flames so the other character(s) can jump across.
