神府矿区岩石浸水膨胀对采空区充水系数影响

Effect of rock soaking expansion to the goaf water filling coefficient in Shenfu mining area

通过对神府矿区煤矿综采工作面采空区探放水工作的研究总结,提出采空区充水系数与采空区地表下沉量及煤层顶底板岩石浸水膨胀性的关系,总结了神府煤田地质条件下充水系数计算修正方法。

Based on the summary of water exploration and drainage in the goaf of the fully mechanized mining face in Shenfu mining area,the relationship between goaf water filling coefficient with descend amount of the earth surface in the goaf and the rock expansibility of the coal seam was revealed. The correction method of the water filling coefficient in Shenfu mining area has been concluded.
