我省冶金矿产资源比较丰富,随着冶金工业发展对原料的需要,矿山生产发展很快,其中仅铁矿石年产量约占全国的十分之一左右。在矿床开发中,地下矿山占主要比重,这些地下矿山的采矿方法,为适应国民经济发展的需要,在寻求高强度、高效率、安全和经济的采矿方法上进行了不断变革,随着采矿工艺的变革,要求装备高
Metallurgy and mineral resources in our province is rich in resources, with the development of metallurgical industry on the needs of raw materials, the rapid development of mine production, of which only about one-tenth of the annual output of iron ore. In the development of the deposits, underground mines dominate. The mining methods of these underground mines, in order to meet the needs of national economic development, are constantly changing in the quest for high-intensity, high-efficiency, safe and economical mining methods. With the development of mining technology The change requires high equipment
