Narrative: We were cleared to taxi to Runway 2L via Alpha and to hold short. The taxiway was mostly bare and dry; as we got down further towards intersection Foxtrot and Golf the taxiway was now compacted snow. I started slowing the airplane and as we got closer to the hold line my co-pilot asked me if I saw the hold line as it was partially obscured by the snow. I answered 'Yes' and started to brake further and then the aircraft started to slide. The co-pilot then asked me again if I saw the hold line and I said 'Yes' but I have no control the braking action was nil; at that point all I could do was to steer the aircraft to the left towards the runway and was able to get it stopped; but we had slid past the hold line by maybe 10-20 ft. My co-pilot informed the Tower that we were unable to stop and had gone past the hold line. The Tower instructed a go-around for the aircraft on final which they were probably 3 miles out. The Tower then cleared us for takeoff and asked us again if the reason we weren't able to stop was because of the braking action and we responded affirmative. We told the Tower that we were sorry we could not stop because of the braking action being nil and he responded that these things happen. The rest was uneventful.


Second narrative: We were taxiing on Taxiway A to Runway 2L in FAI. Between Taxiway F and the hold short lines I asked the Captain if he saw the hold lines because we didn't seem to be stopping. He replied that he was braking and the plane was sliding on the ice. The plane stopped past the hold short line and prior to the runway. We informed Tower and he instructed the aircraft on a 4-5 mile final to go around. The Tower Controller kept us at the same spot and asked about the ice. We told him that we had tried to stop but the braking was poor to nil. Shortly after the report he cleared us for takeoff.  The rest of the flight was uneventful and we were not asked to contact anyone.   It had snowed lightly just before we landed from ZZZ. When we arrived it was sunny and in the 20's and there was no issue braking inbound. The melting from the bit of snow over the compact snow and ice must have created a very slick taxiway at that spot. The lesson learned is that in FAI in the winter all taxiways and runways have the potential to be more slick in places and taxiing very slow at all times is the correct speed.


Synopsis: Air carrier flight crew reported a runway incursion occurred at FAI when they were unable to stop the aircraft at the hold short line because of nil braking action.
