| الوصف: | In underground mining process, variety of roadway surrounding rock structure has obvious non-linearity characteristic, and larger coal-rock dynamic disasters are triggered easily. Existing monitoring technologies for roadway surrounding rock in deep underground are based on data collection of single physical quantity and lack joint monitoring and analysis of multi physical quantities, which are unable to correctly judge deformation state of surrounding rock structure. For above problems, existing monitoring technologies for roadway surrounding rock in deep underground were analyzed including drilling cuttings method, core disking method, stress measuring method, surrounding rock deformation monitoring method, electromagnetic radiation method, acoustic emission method, microseism monitoring method, seism tomography method, etc. A formulation of multi-source and multi-field monitoring system for roadway surrounding rock structure in deep underground was proposed, which was built by use of informatization technology for roadway surrounding rock structure monitoring in deep underground. Key technologies of the informatization technology were expounded form aspects of data perception, collection, transmission and analysis. What's more, some challenges of the informatization technology were discussed including energy supply of sensor nodes in limited environment, unified interaction of heterogeneous sensor and data transmission of time-delay sensitive network. |
