摘要
缓倾斜极薄矿体的开采一直是国内外采矿的难题。根据贵州某镍钼矿缓倾斜极薄矿体赋存条件,结合国外先进无轨采矿设备的应用,提出锚杆护顶机械化削壁充填采矿法,有效地解决了矿山现有开采系统中生产能力小、生产效率低、工人劳动强度大等问题,对镍钼矿资源开发利用具有积极的推广意义。
The mining of gentle dip and extra-narrow ore bodies is a difficult problem at home and abroad. Ac- cording to the occurrence condition of the inclined thin Ni-Mo ore body in Guizhou, combined with advanced applica- tion of trackless mining equipment, mechanized resuing-and-back filling mining method with roof bolting is proposed to solve the problems of low production, low efficiency and the high labor intensity. It has positive significance for Ni-Mo mineral resources development and utilization in the region.
