The utility model discloses a hydraulic control system of a development machine integrating dust extraction and outburst prevention and belongs to the technical field of equipment for excavation. The hydraulic control system of the development machine integrating dust extraction and outburst prevention comprises a development machine mainframe control system, a dedusting draught fan motor control system, an outburst prevention drilling machine control system, a pump station pump and a control oil system. A development machine mainframe, a dedusting draught fan motor and an outburst prevention drilling machine assembly share a set of pump station systems, integration level of the hydraulic system is improved and meanwhile the usage rate of the pump station is improved. The outburst prevention drilling machine control system enlarges drilling scope of the outburst prevention drilling machine, effectively solves the problem that a drilling machine slides when drilling at a big inclination angle, and improves saf
