摘要
分析了神东矿区各可采煤层顶板分类原则、方法及主要特点 ,引入RMR岩体分级系统进行顶板指标测定 ,用采场矿压薄板理论对顶板来压步距及强度进行计算。
The categorizing principle,method and main characteristics of seem roof in shendong mining area are analysed,RMR rock class system is utilized to measure roof parameters,and thin plate theory is utilized to calculate the weighting interval and strenth of roof.
