自溜高压注浆系统在冬瓜山主井的应用

千米深井工作面注浆因地筒深度大，水压高，井内场地狭小，无论在技术，设备，以及施工作业条件上，都具有相当的难度，本文介绍了在冬瓜山主井突水淹井治理过程中，深井自溜高压注浆系统在井底工作面注浆中的应用。

An Application of Gravity High Pressure Grouting System in Main Shaft of Dongguashan Copper Mine

As viewed from technology, equipment and working conditions, the grouting on the working face of 1000m deep shaft was very difficult due to greater shaft depth, high water preeusre and narrow working place in the shaft. In the controlling over water irruption flooding of main shaft in Dougguashan copper mine, the author makes an introduction to an application of gravity high pressure grouting system in the grouting on the working face of shaft floor.
