The invention discloses an underground rock mass engineering ground pressure management and control method. The method comprises the following steps that firstly, a ground pressure displaying rule is researched (Study) and disclosed so as to obtain a stress rise area, a stress reducing area, a tensile stress area and a rock mass moving angle in an underground mine rock mass; secondly, mining area ground pressure transfer (Transter) is guided, and a horizontal cutting roadway and a vertical cutting groove mode are used in the underground mine rock mass to guide the stress in a mining area to be transferred; thirdly, by means of mining area high-stress collapse is used (Use), the impact potential hazard of stress concentration on a top plate of a goaf is eliminated, and meanwhile, a covering layer required by recovery is formed; fourthly, the ground pressure of an operation area is controlled (Control), a stoping roadway is supported by means of an internal reinforcement mode of an anchor rod or an anchor cable
