The invention belongs to the technical field of driving working face anchor protecting equipment, and discloses a full-hydraulic automatic control system of a machine-mounted anchor drilling device for mining. A variable pump is connected with a load sensing multi-way valve. The first linkage of the load sensing multi-way valve is connected with a drilling box motor. The second linkage is connected with a feeding module, and a feeding oil cylinder is connected with the feeding module. An opening A of the third linkage is connected with the feeding module. The fourth linkage is connected with adrilling frame left-and-right swing oil cylinder, and the fifth linkage is connected with a drilling frame front-and-back swing oil cylinder. An opening T1 of a control module is connected with an oil tank, an opening K1 is connected with the load sensing multi-way valve, an opening S1 is connected with a mechanical reversing valve, an opening L1 is connected with the load sensing multi-way valve, an opening Z1 is connected with the load sensing multi-way valve, and an opening M1 is connected with a positioning module. An opening L3 of the positioning module is connected with the first linkage and the second linkage of the load sensing multi-way valve, and an opening T3 is connected with the oil tank. An opening K of the feeding module is connected with the positioning module and a hydraulic-operated water valve. An opening L of the feeding module is connected with the drilling box motor. The full-hydraulic automatic control system of the machine-mounted anchor drilling device for mining has the advantages of being high in automation, clear in functional partition and the like.
