目前国内外开采倾斜矿体,房式法占整个采矿方法的比例分别是24％和42.86％。房式采矿法在倾斜矿体开采中占有如此重要地位的原因是: 1)使用了电动铲运机,使房式法的工人劳动生产率有较大提高,其效率可与崩落法相比; 2)由于使用了各种类型的杆柱支护和液压升降台,扩大了房式法的使用范围; 3)房式法贫化小,一般在8％以下; 4)使用崩落顶板的房式法,随着矿房的回采,及时回收顶柱矿石,这样就简化了回采工艺,提高了矿石回收率。
At present, the ratio of slab mining to inclined mining at home and abroad is 24% and 42.86% respectively. The reason why the room mining method occupies such an important position in the mining of inclined ore bodies is that 1) the use of electric scrapers enables the productivity of laborers in the chamber method to be greatly improved, and its efficiency can be compared with that of the caving method; 2) Due to the use of various types of pole support and hydraulic lifting platform, expanding the use of room method; 3) room method of dilution is small, generally below 8%; 4) With the mining of the mining, timely recovery of the top column ore, thus simplifying the mining process, increased ore recovery.
