摘　　要：漓渚铁矿东Ⅱ号矿体松软破碎,长期难以开采。根据情况,我们在该矿进行了矿块崩落法试验研究并获得了成功。在掘进与支护、双层拉底结构及微机应用等工艺技术上有所创新。依据课题实践,本文对矿体可崩性评价、回采工艺、计算机放矿控制与管理、支护技术、地压监控等内容作了系统的论述。The east 2* oredody of Lizhu iron mine,due to loose and broken ground, has been difficult to mine for a long time. Until recently, an experiment on block caving method has been made and is a success. The technology such as drivage, support, doudle-layer sill cut and microcomputer application etc. has been improved to a more or less degree. According to practice in this mining method,the authors have a systematic discussion on assessment of orebody cavabili-ty, mining technology, computer control of ore drawing, support technique, and ground monitoring and control etc.
