摘要
本文通过以郑州矿务局厚煤层放顶煤工作面为原型的相似材料模拟实验,对单体支柱工作面放顶煤的工艺、采放步距、放煤口间距、放煤次数等参数进行了研究,得出的结果有些己应用于现场并得到了验证。
Based on simulation experiments taking the application of the sublevel caving in Zheng Zhou coal Administration as a pratatype example, this paper studies many the sublevel caving technique parameters such as the span of coal caving the spacing between the mouths of two coal caving tunnels the frequency of coal caving and soon. Some results in this study have been proved in practice.
