Narrative:

Right after or during a position relief briefing; aircraft X came out of approach west bound at 6;000 feet. The aircraft was never on our frequency and was approaching rising terrain to the west. I was conducting OJT. It wasn't until the aircraft was approximately four minutes into our airspace I realized the aircraft was NORDO. I pulled up the mia (minimum IFR altitude) map and saw we needed to climb this aircraft for a 6;300 foot terrain block; in addition to multiple other areas of rising terrain to the west. We attempted to climb the aircraft and received no response. I called approach and told them to reattempt the aircraft; and if they had him still to climb him to 8;000 feet. My trainee was attempting to run the sector which was busy and complex; but the situation was continuing and his proximity to terrain had me worried; so I stopped OJT until we had this cleared up. After taking over; attempting to raise the aircraft on guard; issuing low altitude alerts; I was able to get another aircraft to relay to them on approach frequency and get them to climb.
