An inmate hurled pool balls at officers during violence at HMP Lindholme in which the governor was hit with a rubbish bin.
Simon Booth snapped a pool cue in half and threw it at an officer on September 2, 2018.
Booth ran up to the first floor landing and jumped on to netting between walkways where he was joined by fellow inmate Colin Richardson, said prosecutor Nicola Quinney.
CCTV of the disturbance showed Booth throwing pool balls, hitting one officer on the hand and another on the head.
While officers struggled to restrain the men with shields, another unidentified inmate threw a bin from an upper landing which hit the prison governor.
Richardson denied throwing anything but accepted holding pool balls.
Booth was serving a 54 month sentence for burglaries at the time and Richardso was serving a 32 month sentence for burglary.
Booth, 32 at the time of his court case, pleaded guilty to affray and Richardson, 33, admitted threatening unlawful violence.

Ben McPherson was serving at HMP Moorland, at Hatfield Woodhouse, near Doncaster, when he used a prison issue-plastic knife which had been sharpened to a point to attack another inmate.
Andrew Bailey, prosecuting, told Sheffield Crown Court in August last year that McPherson, then 23, targeted an inmate who was talking to another man with whom he had previously had an altercation.
The victim suffered injuries to his lip and head in the attack.
McPherson told a woman during a phone call he had used a “shank” to stab the victim twice in the face and in the chest and there was “blood spilling out of his face” and as he walked off he had stabbed him again.
He pleaded guilty to possessing an unauthorised weapon and to assault occasioning actual bodily harm.
A judge jailed him for three years, with a two-year extension, having deemed the defendant to be “extremely dangerous”. Photo: Claire Lewis
