【摘要】 根据近几年奥灰岩溶水防治的研究成果和大量的实际调查资料,认为底板突水预测预报的关键是建立突水判据,并依据带压开采中煤层底板承压水渗流场、采动应力场的耦合效应,模拟采动条件下煤层底板破坏状态以及破坏区域的演化规律,建立了底板突水判别式。并以韩城矿务局马沟渠煤矿1108工作面带压开采为例予以说明。
【Abstract】 In this paper, water inrush criterion in coal mining was introduced based on the author’s research work on the prevention and cure of water inrush . In the last, a practical example based on the criterion was given in the paper.
