一、前言随着我国冶金矿山生产向高速度、高强度方向发展,大量崩落采矿法的应用有了迅速的增长。在矿山通风防尘工作中,出现了许多新问题,及时总结和解决这些问题,提高设计质量,对保证矿山生产发展和防止矽尘危害具有重要意义。为此,我们汇集了我国一些采用大量崩落法开采的矿山、主要是有色金属矿山的资料,通过整理认识到,我们对使用崩落法矿山的开 I. Preface As China’s metallurgical and mining production to high-speed, high-strength direction, a large number of caving mining law has enjoyed rapid growth. In mine ventilation and dust prevention work, many new problems have emerged. To timely summarize and solve these problems and improve the design quality are of great significance for ensuring the development of mine production and preventing the harm of silica dust. To this end, we have brought together some of the mines that have been mined using a large number of caving methods in our country, mainly those of non-ferrous metal mines. We have learned by sorting out that we are open to the use of caving mines
