摘要
针对煤层顶板巷道地质特点和锚杆锚固范围,将煤层顶板巷道分为复合型、薄顶、中厚顶和厚顶四类。提出"煤体-锚固"复合承载体概念并分析其受力,推导了支护及煤体参数与上覆均载的关系公式。设计了张集矿胶带顺槽煤层顶板的支护。
Based on the geologic characteristics and anchorage range of the coal roof roadway, is divided into 4 kinds of compound coal-roof, thin coal-roof, medium thick coal-roof and thick coal-roof. Putting forward the concept of ＂coal-anchorage＂ compound bearing whole and analyzing the force on it, deriving the formula on the relationship of the supporting, coal characters and the overlying uniform load. Based on the mechanism, designed the supporting methods of Zhangdi coal mine belt gate roadway.
