自动锯切工艺是雪帕莱区矿山的关键技术英国《石材工业》83年No.8 32～33页英国雪帕莱区几个砂岩露天矿,上复含粘土表层厚150～200英尺。兰特尔亨戚克里夫父子公司露天矿用穿爆法开采砂岩荒料。当一个矿点表土掘完后,崩岩试用泰安炸药导爆线,钻孔注满水,不加填塞,使爆破效应沿炮孔全深均匀扩展,出材率提高。每吨荒料售价30镑,而每吨加工好的石材值200镑,故矿山和加工厂一体化更为经济。该公司采用阿尔沛公司产TRM—S型自动单刀锯
The automatic sawing process is the key technology for the mines in the Snow Palais region. UK “Stone Industry” 83 years No.8 32-33 Several sandstone open pit mines in the snow paree district of the United Kingdom, with a surface layer thickness of 150 to 200 feet. The Rutterheim, Chicleve and Sons Company exploited the explosion method to mine sandstone blocks in open pit mines. After the excavation of an ore site was completed, the Taian explosive explosive detonation line was tested by the rockfall and the borehole was filled with water without filling, so that the blasting effect was evenly spread along the entire depth of the blasthole, and the output rate was improved. The price of a tonne of material per ton is 30 pounds and the value of a pound of stone processed per ton is 200 pounds, so the integration of mines and processing plants is more economical. The company uses Alpei’s TRM-S automatic single-saw
