摘要
利用结构拱的理论,结合矿压观测和俯采时掩护梁上载荷的变化对顾桥矿1113(3)工作面压架原因进行了分析,并对今后工作提出了建议,为顾桥矿开采新工作面和正常开采提供了参考。
using the theory of arch structure and combining with load change on shield-beam,the paper analyzed the causes of pressurizing of hydraulic support for Guqiao mine 1113（3） face that mining by down inclined mining method,and proposed some suggestions for the mining of new faces.
