| 摘 要： | 大同矿务局近距离煤层工作面顶板局部破碎易冒顶,但局部依然坚硬难冒。根据这一特殊地质条件,开发了ZY5000/14/23型液压支架,为“两硬”条件近距离煤层开采顶板支护提供了新的液压支架架型。

| Abstract: | The close-distance coal-seam face by Datong Mining Administration has the condition that part of the roof is broken and easy to fall but other part of the roof is still hard and difficult to fall.According to such special geological conditions,the ZY5000/14/23 shield-type powered support is developed and provides new type of powered support for roof supporting for close-distance coal-seam mining under "two hard" conditions. |
