水库下采煤水情在线自动监测系统

为确保水库下特厚煤层综放开采安全,针对大平煤矿水文地质条件,结合矿井上下工业环网通讯平台,建立了由水库水位监测系统、白垩系含水层水位监测系统和井下矿井工作面涌水量监测系统组成的水库下采煤水情在线自动监测系统;在Windows98/2000/XP环境下,实现了从数据采集处理到水情信息发布的自动化。通过N1S2工作面回采期间运行应用,监测成果反映出白垩系含水层下部含水段底板隔水层破坏、导水,上部风化带含水段与工作面涌水间无水力联系,库下采煤安全可靠。

Hydrological On-line Automatic Monitoring System for Coal Mining Under Reservoir

To ensure safety of caving mining of special thick seam under the reservoir and aiming at the hydrogeological conditions of Daping Coal Mine,combined the upper and lower industrial network communication platform of mine,hydrological on-line automatic monitoring system for coal mining under reservoir consisted of reservoir water level monitoring system,Cretaceous aquifer water level monitoring system and underground working face water inflow monitoring system is set up.Based on Windows98/2000/XP environment,the automation from the data acquisition and processing to hydrological information release is achieved.By running and applying during N1S2 face mining period,monitoring results show that the floor water-resisting layer in lower aquifer segment of the Cretaceous aquifer water floor is failure and water conductivity,the upper weathered zone aquifer segment has no hydraulic connection with face gushing,coal mining under reservoir is safe and reliable.
