摘要
随着充填开采技术的进步,大采高充填支架作为充填开采的主要设备,应用范围越来越广。针对大采高充填支架的稳定性问题和现状,结合ZC12400/30/50充填支架的具体情况,建立了支架稳定性的力学模型,对保证充填支架稳定性的具体措施做了研究。提出可行性的研究结果,解决了"三下"压煤和厚煤层开采问题,对大采高充填支架的应用与推广具有指导意义。
With the filling-mining technology advancement,the large height filling hydraulic support as the main equipment has wide range of applications.This paper does the research about the specific measures of the filling hydraulic support stability,combining with the stability problems and the current situation of the large height filling support,setting up the mechanical model of the filling support stability and specific conditions of the filling support ZC12400/30/50.The feasible study results solve the ＂three down＂ coal and the thick coal seam mining,guiding the application and promotion of the large height filling hydraulic support.
