摘要
在我国,沿空留巷技术得到了非常广泛的应用。为了研究影响沿空留巷底鼓变形的各因素的相互关系,利用AHP层次分析法对6个主要因素所占权重进行计算分析;以某矿2205工作面运输巷作为工程背景,分别对巷道底鼓经历的4个阶段产生的变形量进行计算,得到巷道底鼓总量为895.1mm,为相似条件下的巷道底鼓分析提供了一定的借鉴意义。
In China,the technology of gob-side entry retaining has been widely used.In order to study the relationship between the factors that influence the deformation of floor heave mechanism,the weight of the six main factors is calculated by AHP hierarchy process.Take a coal mine 2205 working face as engineering background,calculation the deformation of each the experience,get the total amount of floor heave of roadway is 895.1 mm,for the similarity analysis of floor heave mechanism of gob-side entry retaining under the conditions of provides the certain reference significance.
