香花岭锡业采掘技术的沿革与发展

History and Development of Excavating and Tunnelling Technology in Xianghualing Tin industry

随着资源的日趋枯竭和社会负担的日益严重，香花岭锡矿自1991年开始连续12年累计亏损达9331万元，2003年6月经破产后重组香花岭锡业公司，严格按现代企业制度运行；当年企业就上缴国家各种税费696．6万元，实现税后利润352万元。增加了高效率采矿方法的应用比例．井巷掘进与支护和凿岩爆破技术有了极大的进步，采掘设备品种、性能和配套程度有了很大提高，矿山安全环境也有所改善。通过对湖南香花岭锡矿矿床地质特征的分析，以及对近年来矿山应用的采掘技术的研究，提出了矿山发展的方向性展望意见。

With resource becoming exhausted and the bear of society becoming large day by day, Xianghualing has lost reach 93,310,000 totally for 12 years in succession from 1991, Recombinated after being through being bankrupt in June 2003, the Company run strictly according to the system of modern enterprise, it turned over 6,966,000 yuan for various expenses of taxation to the country, and realized the after - tax profit of 3, 520,000 yuan. It has increased and the proportion in the highefficiency mining method, and the technology of the well, supports and protects and blows up maked a great progress. The equipment variety, perfornmnce and related in mining and tunneling had great improvement, too. The safety and environment of mine had been improved. This paper analyzed the geological characteristic of mineral to Xianghualing in Hunan, and studied on technology of excavation that the mine is adopted in recent years, the author puts forward the suggestion of directionality prospect of development of mine.
