摘要
我国煤炭垣藏深度在1000—2000m的约占总储量的53．2％，深井建设的平均深度有加速增长的趋势。结合深井快速建井的几个代表性工程介绍钻井法和冻结法凿井技术在深井建设中的应用。探讨了深井建设中支护技术、通风降温技术、防治水技术、施工工艺与装备技术等问题。
Coal reserves at the depth ranging from 1 000 to 2 000 m in China is taken about 53.2 % of the total coal reserves in China. The average depth of the deep mine shafts to be constructed is going to deeper and deeper. The paper introduced the mine shaft drilling and mine shaft freezing sinking technologies applied to mine construction with several representative mine deep shaft rapid construction projects. The paper also discussed the support technology, ventilation and air conditioning technology, water prevention and control technology, construction technology and equipment technology applied in the mine shaft construction.
