国投教学三矿煤炭复采老空水防治技术

Goaf water prevention technology of the repeated mining in SDIC three mine

豫西"三软"煤层矿区,炮采放顶煤后,采空区留有大量残煤,煤炭复采具有重要的意义。在分析区域与局部充水因素的基础上,设计了复采区老空水探放方案。严格执行探放设计方案,进行老空水防治,预防了老空突水事故的发生,保证了煤矿复采的安全。

The＂Three Soft＂coal seam mining, caving working face, left a large number of residual coal in goaf, the coal repeated mining has important signiifcance. On the basis of the analysis of regional and local water iflling factors, design the mining areas of the goaf water probe scheme. Strict implementation of probe design, prevents the goaf water inrush accidents, and ensures the safety of coal mining.
