Suggestion: A multiblock advanced miner that requires a large mining drill (made from different types of materials, with both speed, durability and what resources it can mine taken into account for those materials) that takes damage over time and requires similar maintenance to that of turbines. Also have it mine a larger area than a regular one and it can extract liquids directly through an output hatch without a need for a pump (but make it require an advanced pump in the recipe). Another suggestion for it would be the ability to extract methane from coal ore using water (or sodium bicarbonate/chloride to make it more efficient) in an input hatch and you could add methane to the output of of coal ore in an industrial grinder and is a more efficient way of extracting it than the miner but at the cost of automation (also using sodium bicarbonate/chloride as an optional efficiency booster). This way you can get a lot of methane for the gas turbine, which at the moment, has no efficient way of producing the fuel required on a large scale.
