苏州高岭土矿主要有阳东、阳西、观山三个矿区,虽有悠久的开采历史,但至解放初期仅进行分散的小型露天开采,后来阳西矿3～7线和阳东各矿逐步转入地下开采,并建成新矿井,目前全矿年产量达20多万吨。我国高岭土矿床分布甚广,成矿类型不同,多为中、小型露天开采矿山,随着开采深度增加和剥采比增大,势必出现技术经济上不合理、生产不安全的困难局面。因此,为保证采矿生产的正常进行,由露天矿转入地下开采,是这类矿山必须解决的课题。本文就中国高岭土公司阳东诸露天矿转入地下
There are three main mining areas in Yangling, Yangxi and Guanshan in Suzhou kaolin mine. Although there is a long history of mining, only small scattered open-air mining was carried out in the early days of liberation. Later, ore lines 3-7 in Yangxi Mine and various ore deposits in Yangdong Into the underground mining, and built a new mine, the entire ore annual output of more than 20 million tons. The kaolinite deposits in our country are widely distributed and have different metallogenic types. They are mostly medium and small open-pit mines. With the increase of mining depth and the ratio of stripping and stripping, there will inevitably be a difficult situation where the technology is economically unreasonable and unsafe to produce. Therefore, in order to ensure the normal progress of mining production, it is necessary to solve the problem that such open-pit mines turn underground mining. In this paper, the Chinese kaolin Yangdong open-pit mine into underground
