分析了断层、裂隙以及底板破坏等原因导致的突水类型,探究了隔水层的阻水效果及作用,结果表明,断层以及裂隙结构等破坏了岩体本身的完整性,承压水由煤层底板的薄弱面突出,很容易导致导水通道的形成。实际施工期间,构造带可以一定程度上控制突水问题,但由于强度以及裂隙等因素的限制,隔水层也无法从根本上彻底解决灰岩水对煤层的威胁,由此,在煤层开采过程中,企业应充分重视此问题,做好相应的预防工作。
The types of water inrush caused by faults, fissures and floor failure are analyzed, and the water blocking effect and action of the aquitard are explored. The results show that the faults and the fissure structure destroy the integrity of the rock mass, The weakness of the floor protruding, it is easy to lead to the formation of aqueduct. During the actual construction period, the structural belt can control the water inrush problem to some extent. However, due to the limitation of strength and fissure, the aquitard can not fundamentally solve the threat to the coal seam by the limestone water. Therefore, during the coal mining process , Enterprises should pay full attention to this issue, do a good job of the corresponding prevention.
