云母具有绝缘性好、耐热度高、机械强度大等特点,是极好的电绝缘材料,它被广泛应用于电机工程、无线电工程和电子工程等工业。这些工业的科学技术进展与所用的云母晶体质量有关,尤其是使用大片云母生产敏感性产品时更是如此。在用爆破及可行的地下开采方式揭示云母晶体赋存规律的基础上,本报告概述了研究结果并例举了目前改进采矿方法的趋向,最后提出了一些使劳动强度大的云母开采实现机械化的新设备。
Mica has a good insulation, heat resistance, high mechanical strength and other characteristics, is an excellent electrical insulation material, it is widely used in electrical engineering, radio engineering and electronic engineering industries. The scientific and technological advances in these industries are related to the quality of mica crystals used, especially when using large micas for the production of sensitive products. On the basis of blasting and viable underground mining methods revealing the regularity of micaceous crystals, the present report provides an overview of the results of the study and gives an example of the current trends in improving mining methods. Finally, some proposals are made to mechanize mica mining with high labor intensity new device.
