一、我国留矿法应用基本情况留矿采矿法在我国地下矿山应用较为普遍,各部门应用比例如表1。由表1可知,黄金、有色金属和化工矿山居领先地位,特别是江西、湖南、广东的薄、极薄矿脉的开采达81%之多。近年来我国留矿法除基本方案外,在实践中创造了一些留矿法的变形方案(见表2),

First, the basic situation of the application of retention method in China Mine retention mining method is commonly used in underground mines in China, the proportion of various departments such as Table 1. Table 1 shows that gold, non-ferrous metals and chemical mines occupy a leading position. In particular, the production of thin and ultra-thin veins in Jiangxi, Hunan and Guangdong reaches as much as 81%. In recent years, in addition to the basic method of leaving the mine in our country, in practice, to create a number of deformation methods leaving the mine (see Table 2)
