The invention belongs to the technical field of underground full-automatic jumbolters of coal mines, and particularly relates to an intelligent synchronous electro-hydraulic traveling control system with an automatic speed measuring device for a two-arm jumbolter. The system comprises a hydraulic plunger pump, an explosion-proof motor, functional valve sets, a hydraulic motor, a two-way valve, a walking control handle, a high-speed switching valve, a low-speed switching valve, a speed reducer and a speed measuring device, wherein the plunger pump is driven by the motor; one path of pressure oil is connected with a P port of a two-way valve; an AB port of a first two-way valve of the two-way valve is connected with an AB port of the functional valve set at one side; ports A1 and B1 of the functional valve set are connected with the motor at one side; a second two-way valve AB port of the two-way valve is connected with an AB port of a functional valve set at the other side, and ports A1and B1 of the functional
