摘要
为了适应一次采全高等复杂煤层的开采、提升煤炭资源回收率、提高矿井效益,从大伸缩比液压支架的选型研究出发,通过研究矿井赋存条件、支架选型依据、液压支架的支护强度计算、整体工作面支护的强度模拟分析,得出支架选型主要结果、建议及支架强度分析结果,为特大伸缩比支架的研发提供参考。
In order to adapt to the mining of complex coal seams such as full-height mining in one go,improve the recovery rate of coal resources and the mine efficiency,starting from the research on the selection of hydraulic support with a large telescopic ratio,through studying the conditions of the mine,the basis for support selection,and calculating the support strength of the hydraulic support,simulating and analyzing the strength of the overall working surface support,the main results and suggestions for support selection,and support strength analysis results were obtained,providing reference for the development of extra-large telescopic ratio support.
