摘要(Abstract)：
论述了影响工作面顶板砂岩含水层涌水量大小、持续时间的主要因素及其机理。分析认为 ,自然因素有地下水动力环境、构造复杂程度、砂岩层的岩性、砂岩含水层的厚度 ;其人为因素有工作面的采高、工作面的推进速度、顶板砂岩水的疏放程度。其结论对工作面顶板砂岩水害的防治工作具有重要的指导意义
It is discussed that main factors and mechanics,which influence the water discharging and duration from aquifer of roof sandstones.The results indicate that natural factors include subsurface hydrodynamic environment,structural complexity,lithologic composition of sandstone,thickness of aquifer,meanwhile the artificial factors include shear height and mining speed of work face and degree of roof sandstone dewatering.The conclusion is of great significance for water control of roof sandstone.
