The trial results show that with the disposal of induced caving roof by presplitting blasting and induced caving roof blasting, about 17.8 m in thickness of rock cushion is successfully formed in the inferior abandoned stope, which can bring down the harm of dashing blast of an explosion caused by roof collapse; apparent run-through flaws arise between presplitting blasting holes, and controllable caving is formed in the roof, abrupt collapse of large area roof is prevented, the productional safe surroundings of underground mining is improved; eventually, the resources' reclamation rate is improved from about 70% to 84.6%, and the dilution rate is abated from 25%40% to below 15%, so efficiently withdrawing is actualized.

试验结果表明：采用预裂爆破与诱导崩顶爆破的方法，通过对顶板的诱导崩落处理，成功地在下方采空区形成了厚度为17.8 m左右的岩石缓冲垫层，有效地降低顶板冒落带来的冲击气浪危害；在预裂孔间产生明显的贯通裂隙，从而在顶板上形成诱导可控崩落，防止顶板大面积的突然垮落，改善地下开采安全生产环境；最终资源的回收率由70%左右提高到84.6%，贫化率由25%~40%降低到15%以下，实现了资源的高效回收。

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.

本实验主要利用卵母细胞的乙醇激活、胚胎体外培养和免疫荧光细胞化学方法对小鼠卵母细胞乙醇激活效率、影响因素、孤雌胚类型、发育、原核形成、迁移及早期胚胎卵裂过程中细胞骨架的组装、作用等进行了系统的研究和分析，结果显示：(1)小鼠卵母细胞的乙醇激活结果表明，随着乙醇浓度的升高和作用时间的延长，卵母细胞激活率和发育率都显著提高，但乙醇浓度过高和作用时间过长会导致卵母细胞碎裂率的显著增加，7%乙醇作用卵母细胞7min 为最佳激活条件。
