断层是诱发矿井突水事故的重要影响因素，新汶煤田受奥灰岩溶突水威胁严重，针对断层诱发突水问题，在系统总结新汶煤田矿井断层构造分布特征基础上，建立了断层对奥灰岩溶突水影响定量化分析体系。引入断层影响因子概念，对底板突水危险性进行了定量分析；采用非线性理论对煤矿地质构造发育特征进行定量化研究，揭示了矿井断层分维特征，提出了断层分维特征及其对突水影响危险性分区的原则及方法。采用断层影响因子等值线和断层分维等值线相互融合技术，得到新汶煤田协庄煤矿奥灰岩溶裂隙分布规律。根据不同单元岩溶的富水性，圈定出煤层突水危险区，对煤炭开采防治突水灾害具有指导意义。

Xinwen coalfield was severely threatened by water inrush in ordovician limestone karst region,which was the main factor inducing water inrush accidents in mines.Aiming to solve the water inrush induced by fault,quantitative analysis system on water inrush in ordovician according to fault was established based on a systematical summary of the factures of the distribution and regularity of the fault structure in Xinwen coalfield.The fault influencing factor was in-troduced to quantitatively analyze the risk of the water inrush in floor.Nonlinear theory was adopted to quantitatively study the development characteristics of colliery geological structure.Features of fractal dimension in mining were re-vealed.Features of fractal dimension in fault and risk zoning principle and method of its influence on what inrush were proposed.A method by merging fault influencing factor contour and fault fractal dimension contour was adopted and a distribution on fractures in ordovician limestone karst region in Xinwen coalfield was acquired.According to water abundance in different unit karst,water inrush risk regions was pointed,which was conducive to control the water in-rush disaster in coal mining.
