Problems solved by technology
[0003] The current monitoring of roof disasters generally uses ordinary sensors to monitor roof deformation. This monitoring method is to monitor the roof, which leads to detection only after the disaster has been transmitted to the roof. Once detected, it is already very difficult. Improvement of the roof support, even an accident is imminent, along with threatening the safety of coal mine production

The invention discloses a roof plate disaster monitoring device. By adopting the roof plate disaster monitoring device, not only is a tunnel roof plate monitored in real time, but also deformation andsliding of a tunnel rock layer above the tunnel roof plate can be monitored in real time, the pre-judgment time for tunnel support roof plate disasters can be greatly prolonged, and safe operation ofcoal production can be ensured. As deformation of a rock layer is converted into deformation of a monitoring sleeve or a roof plate sleeve, furthermore radial deformation of the monitoring sleeve andthe roof plate sleeve can be monitored, a rock layer sliding phenomenon of the top of a tunnel can be judged in advance, support can be effectively improved, or corresponding measures for preventingroof plate disasters can be taken, the coal operation stability can be improved, and the coal exploration efficiency can be ensured.
Description
technical field [0001] The invention relates to a roof disaster monitoring device, which belongs to the technical field of roof disaster monitoring equipment used in coal mines. Background technique [0002] In coal mine production, it is necessary to excavate and support the coal mine roadway, and the roof plays an important supporting role in the support of the roadway. After the roof is supported, due to the long-term changes in the roadway rock formation above the roof and the impact of subsequent excavation, the rock formation is prone to slipping and collapse, which may lead to deformation of the roof support in the slightest, and may lead to failure of the roof support in severe cases. Accidents have seriously affected the safety of coal mine support. Roof disaster is one of the most harmful and most prone disasters in coal mine production. [0003] The current monitoring of roof disasters generally uses ordinary sensors to monitor roof deformation. This monitoring ...
