According to the machine body stability control system and method for the cantilever type heading machine, when a cutting arm ascends, a controller converts a cab operation signal or a signal of a remote controller into an instruction and outputs the instruction to a rear proportional valve and an electromagnetic valve, and the rear proportional valve controls a supporting cylinder to stretch out to be in first stress contact with the ground; the electromagnetic valve controls the rear supporting cylinder to continuously abut against the ground to stabilize the machine body; when the cutting arm descends, the controller converts a cab operation signal or a signal of a remote controller into an instruction and outputs the instruction to the front proportional valve, and the front proportional valve controls the shovel plate to be lowered to abut against the ground so as to stabilize the machine body. According to the control system, the rear supporting cylinder and the shovel plate are in stress contact with t
