The prediction of roof convergence in mining area plays an important role in effectively preventing roof accidents and ensuring the safety of mine production. Because the roof pressure in the mine is affected by various natural and human factors, and there is a dynamic and fuzzy nonlinear relationship between the factors. At present, the lack of systematic management will seriously limit the analysis and judgment of the mine safety situation and lead to the occurrence of mine accidents. Strata control instrumentation and monitoring aim at the evaluation and monitoring of the trends of changing rock mechanical parameters such as dilation, load, convergence, stress and axial loading during mining. The objective of this paper is to provide an insight about the monitoring and analysis of convergence in underground coal mines. Also, it provides a comprehensive view of occupational accidents happened in mines along with the roof convergence and risk factors. Finally, the performance analysis of roof convergence rates is analysed.
