【摘要】 新建矿井地表移动参数的确定和覆岩动态破坏规律的研究对矿井的合理规划和安全生产有着重要的指导作用。本文通过岩石力学试验、相似材料模型试验和数值分析结合概率积分法的预计原理,并通过与类似地质采矿条件实测数据的对比分析,研究确定了新建王家岭矿岩层移动的角量参数和地表预计参数；揭示了本矿厚黄土层条件下综放开采覆岩破坏的规律,分析指出了覆岩结构破坏前后的有拱结构和无拱结构,该结构随着工作面的推进,无拱结构周期性循环；研究了在厚黄土层条件下,关键层破断前后,覆岩移动变形、应力变化的规律,描述了黄土层与基岩的相互作用关系,在关键层破断前,黄土层对关键层下部基岩的作用较小,随着关键层的破断,下部岩层压力逐渐增大；揭示了随着工作面的推进距离增大,采空区上方裂隙带高度呈线性的增长趋势。研究结果在王家岭矿得到应用,指导了首采区工作面的布置,对其开采后的破坏程度进行了评估,并提出了村庄的处理建议。更多还原

【Abstract】 Obtaining the surface movement parameters of new mine and studying the laws of overburden rock dynamic damage are important to reasonable planning and safety producing. Through rock mechanics tests, similar material model test and numerical analysis and combining the prediction principle of probability integral method, and comparing with actual measurement data of similar geological and mining conditions, this paper obtained angles parameters and surface prediction parameter of newly-built WANGJIALING MINE, revealed the laws of overburden damage in fully-mechanized sub-level caving under thick loess layer. The arched structure and archless structure were put forward in the bottom strata, and the archless structure looped forward with panel advancing. Under the thick loess layer, around the key strata layer destroyed, the laws of overburden strata movement and deformation and stress changing were studied, and illustrating the interaction between thick loess layer and bedrock, the loess layer affected little to the below strata of key layer before destroyed, with the key layer destroying, the below strata were gradually compressed. This paper also revealed the height of fissure zone above the goaf linearly increasing with panel advancing. The results have been applied to WANGJIALING MINE, directing the panels’ arrangement of first mining area, predicting the damage degree of mining, and putting forward the treatment advice of village above panel.更多还原
