端部放矿模拟是我院无底柱采矿方法组多年研究的课题。在大量放矿模拟试验的基础上,于1973年开始探讨用数学模拟描述放矿基本规律。1975年起试验研究小组将此工作交作者继续进行。作者参考了有关文献,在小组同志们帮助下,于1977年基本上告一段落,并用本组多年积累的大量试验资料进行验证,现发表以供讨论。放矿工作是无底柱分段崩落采矿法中的重要内容之一,放矿工作管理的好坏,直接影响到
End-draining simulation is the subject of many years of research on the pillarless mining method group in our institute. On the basis of a large number of ore-dressing simulation tests, we started to discuss the basic law of ore drawing by mathematical simulation in 1973. Since 1975, the experimental research team has submitted this work to the authors for further work. With reference to the relevant literature, with the help of group comrades, the author has basically come to an end in 1977 and has verified it with a large amount of experimental data accumulated over the years in this group and is published for discussion. Ore drawing work is one of the important contents in subsea column caving mining method. The management of ore drawing and mining work has a direct impact on
