我国脉金矿床的地下开采,对倾斜薄矿体来说,在采矿方法的选择上,至今还没有较为成型的方案可选用.虽然曾用过全面法、房柱法、浅孔留矿法、削壁充填法等,但对于开采这类矿体的采场运搬等工艺问题,没有比较令人满意地解决.致使矿块的生产能力达不到应有的水平,经济效益也不够理想.由此可见,对于倾斜矿体如何寻求一种行之有效的采矿方法,是广大采矿工作者急待解决的艰巨任务.为便于总结、分析、研究和提高,进而筛取最佳方案,现以潼关金矿8号脉的开采技术条件为例,简作如下论述.
Underground mining of vein-gold deposits in our country is not suitable for the selection of mining methods for slant thin ore bodies. Although the comprehensive method, house-pillar method, shallow-hole retention method, However, there is no satisfactory solution to such problems as transportation of stopes for the mining of such ore bodies, resulting in that the production capacity of the ore blocks can not reach the expected level and the economic benefits are not satisfactory. It can be seen that it is an arduous task for the mining workers to solve the problem of how to find an effective mining method for inclined orebody.For the purpose of summarizing, analyzing, researching and improving, and then screening the best solution, Gold mine No. 8 pulse mining technology conditions, for example, the following discussion.
