A high-low pressure integrated roadway grouting reinforcement method is applicable to coal mine roadway support projects. Aiming at deformation and fracture of surrounding rocks of a roadway and fracture distribution rules, injected holes of the surrounding rocks of the roadway are subjected to grouting in sequence by means of low-pressure grouting and high-pressure grouting. The method includes: drilling a rock mass to a designed depth, installing a grouting pipe, and sealing holes with cement; subjecting the roadway surface to guniting to form a surface guniting layer; connecting pipelines, starting a grouting pump, subjecting the superficial rock mass to low-pressure grouting, increasing the grouting pressure after the diffusion range meets design requirements, and opening an expansion pipe under the action of high grouting pressure. The expansion pipe is expanded to stop grout flowing to the superficial surrounding rocks along the grouting holes, so that diffusion of the grout to the superficial rock mass is prevented. The deep rock mass is grouted by high-pressure grout through the grouting pipe to realize high-pressure grouting of the deep surrounding rocks.
