对崩落法全菱形体放出方案的商榷

Discussion on“Whole rhombus drawing”in caving mining Liu Guanghan et al.

在分析无底柱分段崩落法端部放矿方案优缺点的基础上，运用放矿理论、模型试验结果，提出了全菱形体放出方案，并较详细地介绍了其理论基础、参数确定、方案布置，同时探讨了崩落法的发展方向。

Whole rhombus drawing”concept was proposed based on the drawing theories and the testing results through the analysis of pros and cons of end drawing concept,the theoretical principles,parameters as well as the drawing scheme were discussed in more detail,the prospects for the cavining mining methods were given here.
