众所周知,当采用分层崩落法开采急倾斜、特别是具有火灾危险的金属矿床时,金属网假顶的的应用具有重大的意义。 金属网假顶首先应用于煤矿;而应用于金属矿床开采的分层崩落法,不过是40年代才开始(分层崩落法则已有几十年的历史)。在国外应用金属网假顶的成就,还没有在文献中见到;而国内的开滦等煤矿,则是用得比较成功的。
It is well-known that the application of metal netting roofs is of great significance when adopting steep subsidence method to exploit steeply inclined, especially metallogenic deposits with fire danger. Metal mesh roofs are first applied to coal mines; however, the caving method applied to the exploitation of metal deposits only started in the 1940s (the rule of the caving has been for decades). Achievements in the application of metal mesh roof abroad have not been seen in the literature; while the domestic coal mines such as Kailuan are used more successfully.
