| 摘 要： | 介绍了张集矿立井基岩段水文地质和基岩地面预注浆的有关情况。根据井简实测资料，分析基岩裂隙的发育规律、裂隙层界面的浆波充填情况、实际浆液有效扩散半径及堵水效果。认为：立井基岩地面预注浆，不仅能成功地起到堵水的自的．从而缩短工期、降低造价、提高质量，而且还有利于井筒安全揭穿突出谋层，达到安全施工。

| Abstract: | Hydrogeology of the basement section and prior ground injection of pulp into it are described for the shafts of Zhangjimine. Measuring data are based on to analyze the development law of the fissures of basement, the injection situation of pulp around inter-faces of fissured beds, and the effective expanding radius of pulp and waterproof results. It is indicated that prior ground injection of pulpinto the basement of shafts not only succeeds in the waterproof purpose to shorten the work period, decrease the cost and improve the quality,but also does good to the safe cutting of the outbursting coalseam by shafts. |
