You are flying a barge which means you are Omega clone. You have skills for at least some type II (T2) modules (mods). Let’s start with those facts and ask, do you want procurer for ore-only or would you also like to mine ice? If you also want to do ice, are you going to have a dedicated ship for each or just a single ship? My suggestion is to go a single, hybrid route.
Next you start with rigs, which is where “hybrid” comes in. First, a medium core defense field extender to increase general tank. Then both an anti-em and anti-thermal field extender. These two give resistance against specific damage types. The reason for em & thermal is these are the main damage types used by gankers in catalysts. If you don’t tank against them in rigs, you will need to address them in mid slots.
Stick with T1 rigs-only. There is no cost-benefit of using T2 rigs on a barge. There is benefit in putting on a medium ice accelerator rig, but you don’t actually need it to mine ice. It is your choice; either put it on and have a hybrid ship or stick with a ship with only tank rigs.
Similarly, barges are slow to get to warp. And getting to warp is much more important when running away than warp speed when you get there. This is called align time and is also more important to overall travel time than warp speed. Travel time might be important to you if moving around looking for different ore types, or if travelling between ore and ice belts. Here you can add a “low friction nozzle joint” in the rigs. Forget the name, it just means you get into warp, faster.
My hybrid ship suggestion is, 1) core defence, 2) ice accelerator, 3) low friction rigs. You will still be well tanked but can then change your mods for best ore, ice or travel outcomes as required.
In high slots, you have three choices and that you can swap out at any time: 1) 2 x T1 strip miners, which take any ore and are by far the most versatile option, 2) 2 x T2 modulated strips which require a different crystal for every single ore type, also come in T1 & T2 flavours (which must be trained), and usually mean you will never have the correct one in cargo when you need it, 3) 2 x T2 ice harvesters. Best advice is to use T1 for ore & T2 for ice.
In low slots you have about four choices of combinations: 1) 2 x T2 MLUs, 2) 2 x T2 ice harvester upgrades, 3) 2 x T2 inertia stabilizers, 4) DCU plus a second mod of your choice. The idea is to use MLUs on ore, harvester upgrades on ice, stabilizers if travelling (these greatly reduce align time), and the DCU if you want more tank (whether travelling or mining). If you really want more tank then use a DCU and a bulkhead in low, but you will not be able to align very fast under those conditions.
Then you have the mid slots. As suggested by others, you should have at least one T2 medium shield extender and one T2 adaptive invulnerability. The first one is like the core rig and the second is a multi-tasker against the four different types of damage. After that, you decide. If you have a hybrid set of rigs in place, then the suggestion is to add one specific shield mod for anti-em plus one for anti-thermal. But, if wanted you could still use a survey scanner; not needed but these are useful. Or, you could add a propulsion (prop) mod such as an afterburner or your preferred MWD. Limited utility on a barge but still an option.
Finally, drones. Default is probably use T2 hobgoblins as the most powerful. But, the four racial types of drone do different types of damage and sometimes it makes sense to match the drone type against the NPC in the region you are in eg sansha, angel etc have a specific drone that works best against them.
