摘　　要：根据我国煤矿防治水规定和相关规程,突水系数被普遍采用来评价和预测浅埋煤层底板突水危险性。在阐述突水系数理论的基础上,将Arc GIS中的空间叠加功能应用到突水系数的计算中,即分别建立水压和隔水层厚度专题图并进行叠加计算便可得出突水系数,利用自然分级法将突水系数按照临界值分区从而得出突水危险性分区图。结果表明,利用GIS技术计算突水系数准确且行之有效,为突水系数计算提供了一种新途径。According to the regulations and rules of coal mine water control in China,water inrush coefficient is commonly used to evaluate and predict the risk of water inrush from floor of shallow coal seam. Based on the theory of water inrush coefficient, the space superposition function of Arc GIS is applied to the calculation of water inrush coefficient. Namely,water inrush coefficient can be get by establishing thematic maps of hydraulic pressure and thickness of water-resisting floor respectively and making overlay calculation. According to the critical value of water inrush coefficient and by the natural grading method, zoning map of water inrush risk is divided into. The results show that the calculation method of water inrush coefficient by GIS is accurate and effective, and it provides a new way for the calculation of water inrush coefficient.
