空场采矿法在铀矿山使用较早,应用范围较广。如全面采矿法、房柱采矿法、浅眼留矿法以及留矿空场法等,均属此类。现用这些方法采出的矿石量约占地下开采总产量的30％左右。随着发现的小矿体渐多,空场采矿法越来越显示了它的重要性。本文对空场采矿法应用中的几个主要问题作一概略分析。 Opencast mining method used earlier in uranium mines and has a wide range of applications. Such as the comprehensive mining method, the Housing and Pillar Mining Law, shallow stay mining method and the open pit empty method, are of this type. The amount of ore that is produced by these methods now accounts for about 30% of the total underground production. As more small ore bodies are discovered, the law of opencast mining increasingly shows its importance. This article gives a rough analysis of some major problems in the application of the opencast mining method.
