本文概述瓦隆矿业公司为安全、高效、经济地开采厚度小于1.2米的特薄波状矿脉而进行的研究工作。在不足1.2米宽的回采工作面上,矿石的装运由一台专门为此类工作设计的、宽度只有80厘米的铲运机承担。瓦隆矿床的开采工作,从本世纪初就开始了。七十年代以前采完的矿体,大都是厚层矿体(厚达10米)和一些透镜状矿体。不曾发生选别开采问题。在近十年当中,开采 This article outlines the research carried out by Wallon Mining Company in the safe, efficient and economical exploitation of ultra-thin wavy veins less than 1.2 m thick. On mining face less than 1.2 meters wide, the shipment of ore is borne by a scraper of only 80 cm in width designed for such work. The mining of the Wallonia deposit began in the early 2000s. Ore collected before the seventies, mostly thick ore body (up to 10 meters) and some lenticular ore body. No sectoral mining problem occurred. In the last decade, mining
