竖井工程是矿井建设工程的关键,虽然其工程量仅占全矿井巷工程总量的5%左右,但凿井工期却占矿井建设总工期的40%。随着我国国民经济建设的飞跃发展,矿井建设的规模和开采深度都将大为增加,矿井建设的速度要大大加快。这就要求更进一步改进竖井掘进技术,迅速提高竖井掘进速度。
Shaft project is the key to mine construction project. Although the project volume accounts for only about 5% of the total mine shaft project, the shaft sinking period accounts for 40% of the total mine construction period. With the rapid development of our national economy, both the scale of mine construction and the depth of mining will increase greatly, and the speed of mine construction will be greatly accelerated. This requires further improvement of shaft excavation technology and rapid increase of shaft excavation speed.
