The invention discloses a support stability estimating system for a roadway support structure. The support stability estimating system comprises a plurality of support state monitoring units, a first data processor, a parameter output module, a data storing unit, an input keyboard, a second data processor, an alarm prompting unit, a first clock circuit, a second clock circuit, a first timing circuit, a first display unit and a second display unit, wherein the first data processor is used for analyzing and processing monitored data of the support state monitoring units and correspondingly obtaining stress and strain of all support positions at different moments, the second data processor is used for automatically analyzing the effective support time at all the support positions according to the analyzing processing result of the first data processor and data stored in the data storing unit, and the first timing circuit is used for carrying out the automatic statistics on the continuous using time of the monitored roadway support structure. The support stability estimating system is reasonable in design, convenient to install and arrange, easy and convenient to use and operate, good in using effect and capable of automatically estimating the approximate effective support time limit of the support structure according to the support time and the real-time support monitoring result.
Description
technical field [0001] The invention belongs to the technical field of roadway support, in particular to a support stability prediction system for roadway support structures. Background technique [0002] The role of the roadway support structure is to improve the stability of the surrounding rock and control the development speed of the surrounding rock movement to maintain a safe working space. In the actual use process, the roof and the two side anchors in the roadway support structure are the main load-bearing structures. Strong fulcrum, there will be no coal seam side, which will cause the roadway span to increase, resulting in severe roof sinking, instability and collapse. Similarly, the stability and integrity of the roof is also conducive to the stability of the coal side and the reduction of deformation. The two complement each other. Any problem in any link will affect the overall stability of the surrounding rock of the roadway. In the actual use process, as the...
