| 摘 要： | 本文通过对东滩煤矿8条底板巷道受跨采影响变形的实测分析和相似材料模拟实验研究,总结了底板巷道受采动影响的变形规律;分析影响底板巷道的变形的主要因素;提出围岩强度是影响底板巷道变形的最主要因素;研究表明,增加巷道与煤层的法线距离对减小巷道的变形量虽有一定的作用,但这种影响并不明显。本文着重强调:减轻巷道变形的关键在于确定合理的巷道位置及支护方式。

| Abstract: | This paper analyzes the in-situ observation results of the deformation from 8 in-floor-rock roadways of Dongtan colliery and the results of similar material simulation. The deformation rule affected by mining in the in-floor-rock roadways are studied. The main factors which affect the deformation of the in-floor-rock roadways are analyzed. The research results thow that the strength of the surrounding rock is the most important factor which affects the deformation of the in-floor-rock roadways. Increasing the normal distance between the roadways and the coal seam can decrease the deformation of the roadways, but it is not evident. The paper emphasiyes that the key for reducing the deformation of the roadways is to determine the rational position of the roadways and the support patterns. |
