TYZ系列天井钻机的研究及其应用

A RESEARCH AND APPLICATION OF SERIES TYZ RAISE BORING MACHINE

天井钻进法是我国矿山于８０年代推广应用的天井掘进新方法。由于它具有成井速度快、效率高、质量好、作业安全、成本低等一系列优点，因而在我国地下矿山和其它工程中得到广泛应用。本文介绍了该系列天井钻机的设计思想、参数确定、结构形式、工作原理、主要技术性能及在矿山推广应用中取得的良好效果。

The raise boring is a new raising method deployed in China's mines in1980s. Due to a series of advantages such as rapid finishing raise,high efficienly,good qual-ity,low cost and safe operation etc, a wide use of it has been made in China's undergroundmines and other engineerings. The author makes an introduction to design concept, param-eter determination, structure model, working principle and major techmical performance ofthis series of raise boring machine including good results obtained in the deployment ofthem in mines.
