摘　　要：以鲍店煤矿井下新建煤仓为研究对象,依据相似模拟实验,探究新建煤仓对井底岩层运动、煤仓围岩应变特征的影响。具体研究集中在井下分段掘砌过程对已有煤仓、新建煤仓围岩位移量、新建煤仓相同水平高度的测点位移影响,以及对注浆支护的时机、初次支护的锚固点位置预测和指导。基于以上研究,可以实现对鲍店煤矿井下煤仓围岩运动的预测,并为施工设计和掘砌过程中的支护方案提供理论依据。Taking the new coal bunker in Baodian coal mine as the research object,based on the similar simulation experiment,explored the influence of the new coal bunker on the bottom rock movement and the strain characteristics of the surrounding rock of the coal bunker.This research focused on the influence of the underground section excavation process on the displacement of the surrounding rock of the existing coal bunker and the new coal bunker,the displacement of the measuring point at the same horizontal height of the new coal bunker,as well as the prediction and guidance of the timing of grouting support and the location of the anchor point of the initial support.Based on the above research,it can predict the surrounding rock movement of underground bunker in Baodian coal mine,and provide a theoretical basis for the support scheme in the process of excavation and masonry.
