Abstract: The adaptability analysis of hydraulic supports is an important research content to evaluate whether the design and selection of hydraulic supports and the on-site production management operations are scientific and reasonable. Factors of on-site production operation management were barely considered by mining engineers when performing analysis and evaluation of the adaptability of hydraulic supports,leading to a certain lack of understanding of the support capacity. In this paper,a few cases of hydraulic support failure were presented,based on which the concept of effective support ability to evaluate the adaptability of hydraulic support and the corresponding analysis and qualitative evaluation were proposed. Besides,the calculation methods and evaluation criteria of three sub-indicators,the effective support strength,effective initial support force,and effective yielding capacity,which are covered by the evaluation of the effective support capacity of the hydraulic supports,are proposed. Using the proposed evaluation method,the practical application condition of support in the 44305 working face of Yujialiang Coal Mine Shendong Company were evaluated. The results show that effective supporting ability can qualitatively reflect the influence of field operation and management to the adaptability of hydraulic support,and it is an effective index of objective evaluation on the adaptability of hydraulic support and scientific guiding for designing and selection of support and field operation and management.
