为了寻求高效、安全、可靠的天井掘进工艺,七十年代初,我矿在长沙矿山研究院的协助下,开始对天井牙轮钻机进行研制,先后制成了TYZ-300型、TYZ-500K型、TYE-1000型牙轮钻机。本文就牙轮钻机研制、试验和施工过程中的几个问题谈谈看法。 1.根据在本矿、湘东铁矿、潘家冲矿不同岩层中试验的结果表明,中小型牙轮钻机基本能适应井下不同岩石条件的使用; 2.能解决50米以上高难天井的掘进问
In order to seek for an efficient, safe and reliable process of tunnel boring, in the early 1970s, with the assistance of Changsha Research Institute of Minerals, the mine began to develop the patio cone rig. TYZ-300 and TYZ-500K , TYE-1000-type cone drill. This article talked about several issues in the development, testing and construction of roller rigs. 1. According to the results of tests conducted in different strata of this ore, Xiangdong iron mine and Panjiachong ore mine, it shows that the small and medium-sized roller cone drilling rig can basically adapt to the different underground rock conditions; 2. It can solve the problems of tunneling
