摘要
本文通过对特定地质条件下回采巷道围岩的位移、支架的变形及支承压力观测数据的分析研究,提出了两侧均为实体煤时巷道中支承压力的分布规律,对以后这种地质条件下回采顺槽的布置及设计有指导作用。
In this paper,by means of analyzing and studying these date that were acquired by measuring the displacement of surrounding rock,support variation and support pressure in the gate that drif ted in a specific geological condition.The author proposes the abutment pressure distribution law in the gate that is not aff ected by excavation.That has guided for arranging and designing of the kind of gate.Meanwhile,a more suitable support type is proposed.
