我国自然崩落法发展现状与应用展望

说明了自然崩落法崩落的采矿原理，介绍了该法在我国金山店铁矿、铜矿峪铜矿、金川镍矿等地下矿山的应用与试验研究现状，客观阐明了该法目前主要存在现场实践经验不足、生产技术管理落后、新工艺生产效率低、自动化程度不高等问题，并在此基础上论述了该法在我国今后的技术发展方向是提高阶段崩落高度、简化底部结构和采用无轨设备出矿等。

Present Status of Block Caving Development and Its Application Prospect in China

The mining mechanism of block caving method is described. Its application and test research in China's underground mines such as Jinshandian Iron Mine, Tongkuangyu Copper Mine and Jinchuan Nickel Mine are presented. The problems in its application mainly include insufficient experiences in on-site practice, backward production technology management, low production efficiency of new technology, and not high automation degree are expounded objectively. On this basis, it is pointed out that its development in China should be in the driection of raising caving level height, simplifying the bottom structure and using trackless equipment for ore drawing.
