摘要
以东曲矿二采区4#煤的复杂地质条件下的特殊支护为例,论述了相邻极近距离煤层采空区下掘进切眼的联合支护技术,通过实践证明,该技术成果是成功技术经验的总结,为类似条件下的工程提供了科学依据,保证了支护的安全性。
Takes the special support under complicated geological conditions of second mining area Number 4 coal in Dongqu coal mine for example, discusses the combined support technology of neighboring short distance coal seams under goaf the tunneling open - off cut, through the practice proves, this technical achievement is the summary of successful technical experience, provides the scientific basis for the project of similar condition, ensures the security of support.
