【摘要】 本论文以宁夏煤业集团灵新煤矿十四煤顶底板岩性及力学参数为计算基础,利用力学分析、相似材料模拟以及数值模拟的方法对中硬覆岩的导水裂缝带产生发展机理进行了研究,并对其发育过程进行了分析。经分析可知利用变形分析方法确定中硬覆岩的导水裂缝带最大发育高度是一种可行的方法。 通过一系列的分析得出了在水体下应用条带开采方法的原则和适用条件。结合灵新煤矿十四煤的覆岩特性对开采尺寸进行了合理计算。 本论文的研究是对导水裂缝带产生机理及发育过程的探索。应用变形分析方法来分析中硬覆岩导水裂缝带的最大高度具有明显的理论意义。此课题的研究可以为我国一些矿区近水体下压煤开采、水建共同压煤开采提供借鉴。更多还原

【Abstract】 Baced on the mechanics parameter of the fourteenth coal bed in Lingxin- Coal mine,according to the mechanics analysis and similar material simulation and numerical simulation,this dissertation make a study on the creating mechanism and developing law of the water conducted zone height in the moderate hardness cover rocks. After analyses know deformation analysis method is the feasible method to corroborate the largest height of water wonducted zone.By means of a series of analyses,we has obtained the rule and the application term about strip longwall under the water, use the mechanics parameter of the fourteenth coal bed in Lingxin- Coal mine we had calculated the extracing dimensions.The research of this dissertation is probe to guide that water conducted zone brings coming into being and development process . Use the deformation analysis means to analysis the largest height has obvious theory sense .The research of this dissertation can supply reference to mine the coal under water or under the the water and building.更多还原
