摘要
为了研究长壁综放工作面覆岩导水裂隙带高度,根据胡家河矿综放工作面开采技术条件和岩石力学性能参数,建立相似模拟试验模型,对上覆岩层破坏后导水裂隙带高度进行研究,将研究结果与经验公式进行对比,采用回归分析法对经验公式进行修正,并考虑了推进距离对导水裂隙带的影响,从而为预测覆岩导水裂隙带高度提供了一种新的、有效的方法。
In order to study the height of the water flow crack zone in the overburden strata of the fully mechanized longwall top coal caving mining face and to provide the basis to the design of the mining,according to the mining and technical conditions and the rock mechanics performances parameters of the fully mechanized longwall top coal caving mining face in a mine,a similar simulation experiment model was established to study the height of the water flow crack zone after the overburden strata failed.A comparison was conducted on the study results and the empirical formula.A regression analysis method was applied to correct the empirical formula.The advancing distance affected to the water flow crack zone was considered.Thus a new and effective method could be provided to predict the height of the water flow crack zone in the overburden strata.
