摘要
采煤工作面超前支护单体柱施工多依经验进行单体柱打设,不能准确地确定单体柱迎山角度,难以对顶板取得较好的支护效果。给出了一种在倾斜顶板回采巷道单体柱施工中简便、快速确定迎山角度的施工方法,将迎山角度转换为迎山距离。通过测量距离确定迎山角用以指导现场单体柱施工。
In terms of coal mining working face advancing support monomer pillar construction of the monomer pillar,prop-setting angle can not be determine accurately through experience, and hard to achieve good roof supporting effect. The indicated a construction method by converting prop-setting angle to prop-setting distance which determines the prop-setting angle simply in mining roadway with the inclined roof. By measuring the distance to determine prop-setting angle to guide the monomer pillar construction in field.
