摘要
不同厚度基岩条件下支架与围岩的相互作用不尽相同。该文分析了基岩较薄、深厚表土层、临近风化带的地质力学特征,研究了工作面采场支架围岩的相互关系及应力变化,采用载荷经验估算法、理论计算法等计算出液压支架的合理工作阻力,结合地质条件对工作面液压支架进行合理的选型,对类似条件下支架选型有一定的指导意义。
Interaction of different thickness bedrock support and surrounding rock conditions vary. Analysis of the bedrock thin, deep topsoil, geomechanical features of weathered zone near the studied rock mining face in the relationship between the bracket and stress, experience using load estimation method, theoretical calculation method to calculate the hydraulic support reasonable working resistance, combined with the geological conditions on hydraulic Support reasonable selection, the selection of the bracket under similar conditions have some significance.
