龙门峡北矿煤层顶底板灰岩水害分析与治理研究

Study on Analysis and Control of Limestone Water Disaster in Roof and Floor of Longmenxia North Coal Mine

针对龙门峡北矿顶底板强含水地层潜在的矿井突水风险,合理运用水文地质物探技术,超前探明顶、底板含水层导水通道突水是矿井涌水的主要来源,提出有效治理方案对矿井强含水层截流区域水害进行治理。

For the potential inrush water risk of strong aquifer in the roof and floor of Longmenxia north mine, hydrogeological geophysical exploration technology was rationally used to ascertain specific circumstances of water hearing rock stratum in advance. The results showed that inrush channel of roof and floor is the main source of mine water inrush. Effective governance scheme was proposed to control mine strong aquifer flood.
