Narrative:

Was engaged in d-side training on sector 8. Aircraft X called on the ground from dij airport requesting an IFR clearance. At the time we had numerous jac arrivals and an overflight at 170. We called sector 16 to apreq the departure headed to the east to boy. Sector 16 approved the aircraft climbing to FL290. To alleviate any conflict with traffic and terrain; we issued the lamon two departure which takes the aircraft to the northwest to gain altitude prior to turning east. An altitude of 160 was issued and a void time given.aircraft X departed some minutes later and we immediately recognized that the aircraft was not flying the assigned departure and was headed into high terrain still climbing. The r-side controller advised the pilot of a low altitude alert and asked [if] they were flying the lamon departure in which the pilot said yes. Clearly; they were not and continued east into even higher terrain. Another low altitude alert was issued and the controller asked if the pilot had the terrain in sight in which they responded yes. During the time of the 2 low altitude alerts; the aircraft was in an mia of 134 and subsequently 158.a departure procedure was issued to the pilot for both terrain and traffic. If a dp or SID is issued; the pilot needs to comply.
