摘 要:锡矿山锑矿矿体属于典型的缓倾斜似层状中厚类型矿体,其采矿时根据矿体产状、矿石品位及地表允许陷落情况需分别采用充填法和空场房柱法开采。随着开采向纵深发展,矿体由缓倾斜趋于倾斜,且由厚趋薄,中段高度也由36 m改为50 m。单纯依靠充填法和空场房柱法已难以适应矿体变化的需要。针对矿体不同形态试验研究杆柱砂浆充填采矿法、壁式充填(水压支柱护顶)采矿法、倾斜(急倾斜)薄矿体上向连续采矿法,以满足矿体的开采要求。Xikuangshan antimony ore body belongs to a typical gently inclined layered medium thick type of ore body.During mining,filling method and open field room pillar method need to be used respectively based on the ore body's occurrence,ore grade,and surface subsidence conditions.As mining deepens,the ore body tends to tilt from gentle,and from thick to thin,and the height of the middle section is also changed from 36 m to 50 m.Relying solely on filling method and open field room pillar method is no longer suitable for the needs of ore body changes.This paper focused on the experimental research of pillar mortar filling mining method,wall filling(water pressure pillar roof protection)mining method,and inclined(steeply inclined)thin ore body upward continuous mining method for different forms of ore bodies,meeting meet the mining requirements of the ore body.
