摘要
为了准确实测回采煤层顶板导水裂隙带高度,避免顶板裂隙水害事故发生,解决传统地面打钻方法确定断裂带高度时,精度低、效率差等难题,四侯煤矿地测防治水科通过研究,对3108工作面回采的3#煤层顶板采取"双端胶囊堵水"观测技术实测煤层顶板裂隙带高度。采用该技术后确定了3^#煤层顶板裂隙带高度为47 m。
In order to accurately measure the height of water-conductingting fissure zone in the roof of mining coal seam, avoid the occurrence of the water hazard accident in the roof, and solve the problems of low precision and poor efficiency when the fault zone height is determined by the traditional ground drilling method, the geological survey and water prevention and control department of Sihou Coal Mine adopted the observation technology of "double end capsule water plugging" to measure the height of coal seam roof fracture zone of No.3 coal seam in 3108 working face. After adopting this technology, the height of fracture zone of the 3^# coal seam roof is 47 m.
