摘　　要：文中简要介绍了高阶段自然崩落法的实质及主要方案,指出该采矿法放矿时的特点;重点阐述了在待崩落矿体下放矿和在崩落围岩覆盖条件下放矿的这样两个控制原理不同的放矿阶段;根据所取得的理论研究成果,开发出可用于指导生产的微机控制放矿软件系统。该项成果进一步完善了放矿理论与应用体系,使矿山管理科学化向前迈进进了一大步。This paper briefly introduces the principal and main forms of block caving system, points out the ore-drawing characteristics, and discusses in detail that the ore-drawing processes with and without waste overburden are two different stages and have different control principals. Based on this theory, the PC control software system has been developed and is used to direct the production. This achievement has perfected the ore-drawing theory and application field and has advanced a significant step forwards to the scientific management of ore-drawing processes.
