鹤煤十矿大面积老空水治理技术实践

Practices on Large Area Goaf Water Control Technology Applied to Hebi No.10 Coal Mine

煤矿采空区积水是威胁矿井安全生产的灾害之一,对其进行防治具有重要意义。鹤煤十矿13采区南翼浅部大面积老空积水严重威胁矿井整体开拓布置。文章在综合分析13采区地质及水文地质条件下,提出了"物探先行—钻探疏放—巷探验证"的治理技术方案,实践表明,彻底消除了老空积水对矿井安全的威胁,确保了矿井安全生产。

A ponding in a mining goaf would be one of the mine disasters to the mine safety production and prevention and control of the ponding would have important significances. A large area ponding in a goaf at the south wing of No. 13 mining block of Hebi No. 10 Mine seriously imperiled a completed development layout of the mine. Under a comprehensive analysis on geological and hydrological conditions of No. 13 mining block,a control technical plan with ＂a geophysical exploration first- water drainage and discharging with drilling exploration- mine gateway verification＂was provided.The practices showed that the ponding in the mining goaf threatened to the mine safety were completely eliminated and the mine safety production was ensured.
