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。
In order to obtain the characteristics of overburden strata in shallow depth, thin bedrock and thick sand area, based on the division of the three strata in the overburden strata of the stope, the 120408 face of the coalmine in the Shenhua Shendong Coal Group was selected as the research object, The relationship between the activity of overlying strata in mining and the propulsion degree of working face provides some theoretical basis for engineering practice.
