立井井筒过高压强含水层防治水方法技术研究

摘要

South auxiliary shaft of gaocheng coal mine in the mining area north west, above coal bed roofs three packs are thick a circle gate group section to three sections of positions, it 's 200 meters, the aquosity is strong; Coal bed ledger wall Taiyuan group upside L7-8 calcareous rock, the lower segment L1-4 calcareous rock watery is rich, the hydraulic pressure reaches 5MPa.After the research and the exploration, summarized“searched, stops up, directs, to keep off, the platoon, the truncation, seals” the vertical shaft well chamber synthesis to guard against regulates waterways the construction technology, has effectively prevented the well chamber flood accident occurrence.%告成煤矿南翼副井井筒处于矿区西南部，二1煤层顶板以上三叠系圈门组一段至三段层位较厚，近200米，含水性较强；二1煤层底板太原群上段L7-8灰岩、下段L1-4灰岩含水较丰富，水压达5MPa。经过研究与探索，总结出了“探、堵、引、挡、排、截、封”立井井筒综合防治水施工技术，有效预防了井筒水害事故的发生。
