The stress monitoring filling body comprises a filling body, at least three three-dimensional stress sensors are arranged on the filling body in the length direction, and the three-dimensional stress sensors are arranged at intervals from the upper side of one end of the filling body to the lower side of the other end of the filling body. The stress condition of the filling body can be analyzed in real time through the three-dimensional stress sensor, and the optimal safety strength of the filling body is obtained according to the stress condition in combination with the change and stability condition of the field filling body so as to ensure the safety of the top plate. After mining is finished, continuous stress monitoring is carried out on the stress condition of the filling body, and monitoring and early warning are carried out on the ground pressure of the goaf. 一种应力监测充填体及监测系统，包括充填体本体，充填体本体沿长度方向分别布设有至少三个三维应力传感器，且各三维应力传感器从充填体本体的一端上侧向另一端下侧间隔布置。通过三维应力传感器能够实时分析充填体的受力情况，根据受力情况结合现场充填体的变化和稳定情况，得出充填体最佳安全强度来保证顶板的
