中间矿堆地下通廊顶板压力计算方法分析

Analysis of Calculation Method for Roof Pressure of Underground Passageway of Intermediate Mine Pile

中间矿堆通廊顶面的荷载压力尚无明确、统一的计算方法。目前工程技术人员主要采用部分荷载法和全荷载法进行计算。从相关理论出发,详细分析了两种方法取用的依据,探讨了各自的适用条件、可行性与可靠性,并总结出中间矿堆地下通廊顶板压力取值的合理方法。

There is no definite and unified calculation method for the load pressure on the top surface of the corridor of the intermediate ore pile. At present, engineers and technicians mainly use partial load method and full load method for calculation. Based on the relevant theories, the basis of the two methods is analyzed in detail, their applicable conditions, feasibility and reliability are discussed, and the reasonable method of taking the roof pressure of the underground corridor of the intermediate ore pile is summarized.
