摘要
本文论证了在使用现有的破土排渣工具时,沉井下沉100m的可能性。分析了在实践中经常出现的深井难沉现象的诸多原因,提出了克服的方法。沉井成败的关键是防偏与纠偏,通过改进工具,沉深200m,偏斜率小于5%是可以作到的。
The possibility of drum shaft to sink down 100 m by means ofthe available breaking and conveying tools is demonstrated. After analysing the causes about the difficulties often arising in practice of deep shaft to sink down, the method to overcome them is presented. The crux of success or failure under construction of drum shaft lies in protecting deviation and correcting deviation. Throngh improving tools the drum shaft to sink down over 200m with the deviation ratio less than 5% is possible.
