煤矿床裂隙喀斯特水,特别是涉及突水的问题,是很复杂的问题.突水通道,是突水体系中可供直接观察的最后环节. 突水通道的形成决定着突水的发生,它的形状大小又决定着出水量的变化.但是,对于突水具有如此重要意义的突水通道研究,迄今仍有待于全面的开展. 文中阐明了突水通道的概念和形成.对于突水通道、突水通道压降和实际出水量之间的相互关系,也提出了作者的一些新的看法.最后,分析了突水通道在安全生产中的实际意义.
The fractured karst water in coal mines, especially the problems related to water inrush, is a complex issue. The water inrush channel, which is the last link in the water inrush system, can be observed directly. The formation of water inrush channel determines the occurrence of water inrush The shape and size of water inrush determine the change of water output.But the research on water inrush channel, which is of great importance to water inrush, has yet to be fully developed.This paper clarifies the concept and formation of water inrush channel.For water inrush channel, The relationship between the pressure drop of water inrush channel and the actual water discharge also puts forward some new ideas of the author.Finally, the actual significance of water inrush channel in safety production is analyzed.
