The invention provides a roadway surrounding rock mine pressure detection device and method, and relates to the technical field of roadway construction.The roadway surrounding rock mine pressure detection device comprises a connecting assembly, the connecting assembly is suitable for being placed in roadway surrounding rock, and an upper stress sensor, a lower stress sensor, a front stress sensor and a rear stress sensor are connected to the connecting assembly; the upper stress and the lower stress of the surrounding rock of the roadway and the front stress and the rear stress in the length direction of the roadway are monitored respectively, then the surrounding rock stress capable of influencing the deformation of the surrounding rock of the roadway is monitored in real time, and in addition, the shock sensor is arranged on the connecting assembly so that the impact vibration condition borne by the surrounding rock of the roadway can be monitored in real time. Monitoring of surrounding rock stress and impact vibration is achieved on one device at the same time, and the problem that it is difficult to monitor a plurality of variables such as surrounding rock stress and impact vibration in a unified and real-time mode at the same time point in an existing monitoring mode is solved.
Description
technical field [0001] The invention relates to the technical field of roadway construction, in particular to a device and method for detecting rock pressure in the surrounding rock of a roadway. Background technique [0002] The roadway is a variety of passages drilled between the surface and the coal body to carry out ore transportation, ventilation, drainage, pedestrians and other work. The roadway is unavoidably affected by the mining of the mining face during its use. Since the mining of the mining face forms a high stress concentration area on both sides of the surrounding rock of the roadway, when the corresponding kγH value on both sides of the surrounding rock of the roadway (where k is Stress concentration factor; γ is the bulk density of the roof rock layer, kg / m 3 ; H is the depth of burial, m) When the limit of the roof rock layer is exceeded, the roof will break and produce shock vibration, high stress concentration and shock vibration act on the surrounding r...
