长锚索和短锚杆的联合应用可有效地加固充填法采场的顶板。欲在我国井下采场实现这一新技术,其中的重要问题之一是要有效解决安装长锚索并向孔内注浆的机具问题。为此,长沙矿山研究院和铜陵有色金属公司凤凰山铜矿、设计研究院从1981年初开始,对此进行了研制,并在凤凰山铜矿进行了试验,取得了良好的效果。这些机具包括
The combined application of long anchor and short anchor can effectively reinforce the roof of filling method. One of the important issues to achieve this new technology in underground stopes in our country is to effectively solve the problem of the equipment for installing long anchors and grouting holes. To this end, Changsha Institute of Mining and Tongling Nonferrous Metals Company Phoenix Mountain Copper, Design and Research Institute from the beginning of 1981, which was developed, and the Phoenix Mountain Copper Mine has been tested and achieved good results. These machines include
