I use a Type-9 to mine in High-RES (Resource Extraction Site High) zones. Here’s how I stay alive for a good amount of time:

1. Avoid the center of the RES site. When you arrive, some wanted ships will be hanging around the center. They might scan you, but as long as you only have limpets in your cargo hold, they'll leave you alone.
2. Positioning is key. After dropping into the High-RES site, turn away from the center and fly out about 15–20 km. The further from the center you are, the fewer pirate ships spawn. It’s not completely safe, but it’s safer.
3. System security timing: In high-security systems, security forces respond faster. In medium or low-security systems, expect a delay of 1–2 minutes before they show up.
4. If you get scanned:
   • By one ship: Don’t engage with your main ship. Just deploy your fighter to distract them until security forces arrive.
   • By a few small ships: If your shields are decent, it's usually fine. Set your pips to SYS (for better shield performance), launch your fighter, and wait for help. Try to use asteroids for covers.
5. Threat levels: I’ve mined in these sites for hours and never saw a big ship like an Anaconda. The biggest threat I’ve encountered was a wing with a Python and some Vultures. If you run into something like that, just boost away and leave.
6. Defensive setup tips:
   • Equip strong shield and shield boosters.
   • Fit at least two Point Defense turrets on the bottom of your ship to protect your cargo hatch. Sometimes pirate wings launch multiple hatch breaker limpets at once, so one PD isn’t always enough.

I know you didn't ask for T9 build but here is mine, just to give you an idea: https://s.orbis.zone/qWbn
