薄矿床开采有两种类型:一是脉状矿床的薄矿脉;二是层状矿床的薄矿体。由于矿床要素和开采工艺的不同,将薄矿床开采的采矿方法与厚矿体分别进行研究,是非常必要的。一、三十年来改革方案的归纳为了便于分析和研究问题,现将三十年来我国薄矿床矿山生产中使用和试验过的各种采矿方法,作一个简要的归纳,列入表1。由表1可见,这些采矿方法可分四大类,具体的采矿方法近20种,而各种变型方 There are two types of thin-bed deposits: the thin veins of vein-shaped deposits and the thin-bedded ore bodies. Due to the difference between ore deposit elements and mining processes, it is necessary to study separately the mining methods of thin deposits and thick ore bodies. Summarization of reform programs in the past 30 years In order to facilitate the analysis and study of problems, a brief summary of the various mining methods used and tested in the production of thin-bed mines in China for 30 years is presented in Table 1 below. Can be seen from Table 1, these mining methods can be divided into four categories, the specific method of mining nearly 20 species, while a variety of variants
