The invention discloses a mine support capable of monitoring rock burst in real time. The mine support can detect the rock burst or impact the ground pressure while supporting a roadway and comprises a supporting leg assembly and a support assembly. A pressure sensor is arranged on the supporting leg assembly, and the rock burst of the roadway can be monitored in real time through the pressure sensor. Various energy absorbing and receding structures are arranged on the support assembly and the supporting leg assembly, instant energy absorption and timely receding on the rock burst can be achieved, and the impact resistance of the support is improved. According to the mine support, the instant impact force of the pressure sensor can be adjusted easily and conveniently, and the pressure sensor can be effectively protected. The pressure sensor is easy and convenient to replace, the maintenance cost in the using process is greatly reduced, and the difficulty is greatly lowered. According to the mine support, the rock burst is detected in real time through the pressure sensor, the precision is higher, and the reliability and durability are superior to those of an existing rock burst detecting device.
