南非莱诺石膏工业公司一矿使用1900SM连续采矿机取代钻孔爆破法进行开采,提高了生产率、降低了成本。该矿于1983年开始生产,用穿、爆法开采石膏5万吨/年,后用装载机与汽车装运,增至25万吨/年。为了一次完成松动、破碎和装载,1984年10月开始使用1900SM型连续采矿机,生产率比预计的80吨/小时平均提高25%。在正常条件下,该 The first mining operation at Leno Gypsum Industries in South Africa used the 1900SM continuous mining machine instead of the borehole blasting method to increase productivity and reduce costs. The mine started production in 1983, using wear, blasting method gypsum mining 50,000 tons / year, after the loader and car shipment, increased to 250,000 tons / year. In order to complete the loosening, crushing and loading at one time, the 1900SM continuous mining machine was started in October 1984 and resulted in an average increase of 25% over the expected 80 t / h. Under normal conditions, the
