Narrative:

Aircraft #1 aircraft X uni climbing wbound to 10000 ft. Aircraft #2 aircraft Y cmh jqf sebound at 9000 ft. Hts approach called to appreq an altitude on aircraft X departing wbound. We did not have the handoff yet on aircraft Y; and I released 10000 ft. We then combined 2 sectors; which included aircraft Y at 9000 ft. 2 mins; aircraft X departed and called on frequency about 5200 ft. The controller was unable to stop the aircraft below aircraft Y. Aircraft X later informed us he was climbing at 3800 FPM.

Title: ZID CTLR EXPERIENCED OPERROR AT APPROX 8000 FT WHEN DEP FROM ADJACENT APCH CTLR AIRSPACE ASCENDED THROUGH OCCUPIED ALT.

Narrative: ACFT #1 ACFT X UNI CLBING WBOUND TO 10000 FT. ACFT #2 ACFT Y CMH JQF SEBOUND AT 9000 FT. HTS APCH CALLED TO APPREQ AN ALT ON ACFT X DEPARTING WBOUND. WE DID NOT HAVE THE HDOF YET ON ACFT Y; AND I RELEASED 10000 FT. WE THEN COMBINED 2 SECTORS; WHICH INCLUDED ACFT Y AT 9000 FT. 2 MINS; ACFT X DEPARTED AND CALLED ON FREQ ABOUT 5200 FT. THE CTLR WAS UNABLE TO STOP THE ACFT BELOW ACFT Y. ACFT X LATER INFORMED US HE WAS CLBING AT 3800 FPM.
