Zusammenfassung:	The utility model provides a hydraulic control system for an anti-twisting device of an open caisson type heading machine. The anti-twisting device of the open caisson type heading machine comprises a telescopic arm, a clamping oil cylinder and an anti-twisting oil cylinder, the hydraulic control system comprises a main oil way and a driving oil way which are communicated with each other; the main oil way comprises a hydraulic pump and a proportional pressure reducing valve, and oil is pumped through the hydraulic pump and enters the driving oil way after being subjected to pressure regulation through the proportional pressure reducing valve. The driving oil way comprises a first driving branch oil way and a second driving branch oil way; a throttling valve is arranged on the first driving branch oil way, and oil liquid subjected to pressure regulation through the proportional pressure reducing valve enters a rodless cavity of the clamping oil cylinder through the throttling valve; an electromagnetic reversin
