肥城煤田滑动构造在矿井水害中的作用

Influence of Sliding Structure on Water Disaster of Coal Mine in Feicheng Coal Field

总结了肥城煤田滑动构造的基本特征，深入地研究了滑动构造与矿井水害之间的关系．认为肥城煤田的滑动构造强化了五灰和奥灰之间的水力联系，造成了该煤田水文地质块段的东西差异性，同时，滑动构造还造成了煤田浅部和深部煤层底板隔水层厚度的变化，从而影响浅部和深部底板突水的概率．探讨了滑动构造与导高的关系，提出了应力溶蚀机理，揭示了滑动构造影响下的突水特点．

Basic characteristics of sliding structure of Feicheng coal field is summarized. Relationship between sliding structure and water disaster of coal mine is researched in detail. The sliding structure of Feicheng coal field is thought to have strengthened the water connection between the fifth limestone and the Ordovician limestone, causing a difference between the east hydrogeological block and the west one in the coal field, and making the thickness of water resisting layer of seam floor in both shallow and deep levels changed, which has some influence on probability of water burst from floor. The relationship between sliding structure and the hight of water conducted zone is investigated, the stress corrosion mechanism is put forward and the water burst characteristics influenced by sliding structure is revealed.
