浅埋覆岩移动规律的相似模拟实验研究

Experimental Study on Similarity Simulation of Moving Law of Shallow Overburden

为了得到浅埋深、薄基岩、厚风沙地区采场覆岩活动特征,基于采场覆岩三带的划分,以神华神东煤炭集团补连塔煤矿120408工作面为研究对象,得到开采过程中采动覆岩的活动与工作面推进度的关系,为工程实践提供一些理论依据。

For receiving shallow buried depth, thin bedrock and thick sand area activity characteristics of overburden rock, based on the division of the three zones of overburden rock, with Shenhua east tower coal group in Qilianta coal mine 120408 working face as the research object, get the relationship of working face advance degree and the activity of overburden rock in the process of mining activity, provide some theoretical basis for engineering practice.
