随着我国钢铁工业的不断发展,锰矿石的需要量不断增加。为了更好地发挥我县资源优势,发展锰矿生产,增加产量,提高质量,为钢铁工业多提供锰矿原料,支援“四化”建设。一九八四年三月省锰矿公司和我公司签订了省县联营对三坑锰矿进行技术改造的协议。接着对三坑锰矿P—1号矿体进行了地质补勘工作,获得了B+C级储量49万吨和D级储量13万吨的成果。八四年九至十一月中旬省冶金设计院和我公司有关技术人员对该矿各项工程进行了设计,为八五年技改工作顺利进行打下了
With the continuous development of China’s steel industry, manganese ore demand continues to increase. In order to give full play to our county resources advantages, develop manganese ore production, increase production, improve quality, provide more manganese ore raw materials for the steel industry, support the “four modernizations” construction. In March 1984, the provincial manganese company signed an agreement with our company for the technical transformation of the Sankeng manganese mine at the provincial and county levels. Subsequently, the geological prospecting work was carried out on the P-1 ore body of the Sankeng manganese mine and the achievements of 490,000 tons of B + C reserves and 130,000 tons of D-class reserves were obtained. From September to November mid-1984, the provincial Metallurgical Design Institute and the relevant technical personnel of our company have designed the various projects of the mine to lay a solid foundation for the technical renovation work in 1985
