选择合理的采矿方法是提高矿山劳动生产率,降低开采成本的重要途径。因此,寻求一种工效高、采准切割工作量小、作业安全的采矿方法有着重要的意义。本文就有关該矿采矿方法的几个問題談談我們的几点分析意見,供参考。一、地质特征簡介該矿是湖相沉积石膏矿床,矿区构造簡单,无大地质构造。膏层沿走向变化稳定,沿傾斜稍有輕微的折曲和分支复合現象。膏层傾角为6～8℃,走向东西,傾向南。矿石为白色纖維石膏,普氏硬度系数(f)为2～3。可采膏组为九組。目前开采第二水平第七膏組,該組石膏为
Choosing a reasonable mining method is an important way to improve mine labor productivity and reduce mining costs. Therefore, it is of great importance to seek a mining method that has high work efficiency, low work load and safe operation. This article on the mining method of several questions about our analysis of some of the views for reference. First, the geological characteristics Introduction The mine is lacustrine deposition gypsum deposits, mining area structure is simple, without major geological structure. The plaster layer changes steadily along the strike, with a slight slight bend and branch compound along the slope. Pasty tilt angle of 6 ~ 8 ℃, to something, tend to south. Ore white gypsum, Platts hardness (f) of 2 to 3. Recoverable paste group for the nine groups. The current second level of mining the seventh group, the group of gypsum for
