矿压引起煤层底板的破坏现象已被人们所认识。然而,矿压对煤层底板的起始破坏部位及发展形成过程却被人们所忽视,这是煤层底板穷水研究中的一个关键性问题,因为煤层底板破坏部位与岩体“原始张裂”的相互关系决定着煤层底板突水条件。本文则以研究这个问题,为目的,(提出煤层底板岩体移动的“零位破坏”理论。 Underground pressure caused by the destruction of seam floor has been recognized. However, the pressure of coal seam on the floor of the initial destruction of the site and the formation of the formation process has been neglected, which is a key issue in the study of coal seam floor water, because the destruction of coal seam floor and rock mass “original” crack Interrelation determines the coal floor water inrush conditions. In this paper, to study this issue for the purpose of (proposed movement of coal seam floor “zero failure” theory.
