The invention relates to an intelligent
coal mine support, which comprises a supporting plate, the supporting plate is installed with a connecting plate in a hinging manner, the connecting plate is connected with a shielding beam, the shielding beam is installed with a top beam in the hinging manner, the supporting plate is provided with a No.1
hydraulic cylinder connected with the top beam in thehinging manner, the top beam is connected with a supporting device which prevents the top beam from being overload rotating, a reinforcing device for increasing the
bearing capacity of the top beam is also installed on the top beam; and the No.1
hydraulic cylinder, the supporting device and the reinforcing device are connected with a controller. The intelligent
coal mine support can support the top beam through the cooperation of a check rod and a
ratchet wheel to prevent the underground collapse caused by the overturn of the top beam; the intelligent
coal mine support can enhance the jackingforce of a No. 2
hydraulic cylinder through the cooperation of the reinforcing rod and a U-shaped plate to prevent the collapse of the No. 2 hydraulic cylinder caused by the overturn of the top beamduring the supporting process; the intelligent coal mine support can drive a chain wheel to rotate to release a
pendulum rod quickly through a chain, and meanwhile a No. 3 hydraulic cylinder drives asupport rod to support the top beam to prevent the overload collapse of the top beam so as to
gain time for workers to escape.
