摘　　要：为了解决特厚煤层沿空掘巷小煤柱工作面防治水难题,对防治水现场工作提供有效的指导,消除掘进过程中的安全隐患,提出构建小煤柱沿空掘巷井上下矿井水文联合监测安全保障体系,对采空区积水的水位标高、积水深度、积水量等信息进行实时监测;针对监测信息编制科学合理的疏放水设计方案,对采空区积水进行安全、高效、快速疏放。方案实施后,掘进所受到的临空水患影响消除,有力地保障了小煤柱巷道的安全掘进。To solve the problems of water control at small-pillar working face in gob-side entry driving with ultra-thick coal seam,the authors proposes the integrated monitoring safety guarantee system for up-down mine hydrology in small-pillar gob-side entry driving,in which the real-time monitoring of the water level elevation,the seeper depth and the seeper quantity in goaf is carried out;and safety,high-efficiency and rapid drainage is implemented according to the scientific and reasonable water drainage design scheme based on the monitoring data,eliminating the water disaster and guaranteeing the safety tunneling in small-pillar roadway.
