摘要
本文在大量实验等工作的基础上,对门城煤柱开采可行性程度进行了详细的分析和论证,着重指出煤柱开采合理方案中值得重视的支承压力峰值、刀柱合理宽度、悬板极限跨度等重要参数。
The practicable degree of Men Cheng-pillaring is analysed and proved in great detail based on a vast amount of experiments and the important basic parameters in reasonable plan of pillaring such as peak value of supporting pressure, the reasonable width of knife-pillar and the ultimate span of suspension board etc, are pointed out emphatically in this paper.
