在採矿作业中,推广硬质合金钎头的工作,到目前为止,基本上已趨于鞏固的阶段。如何更进一步地鞏固並更充分地发挥它的优越性,提高生产效率,降低生产成本,为国家工业化积累大量的资金,这是今后试验工作的中心任务。在目前,虽然未曾徹底地进行“合理地利用硬质合金钎头,降低生产成本”的试验,但从最近钎头磨钝程度的掌握上,即每磨钝一次的鑿孔总深度,每磨钝一次标准修磨程度以及全部修磨的标准次数方面来看,就不难想像影响提高成本的程度。因此,我们结合着鑛山岩石情况,並以岩石分类及硬质合金钎头试验为基础,进行了不同的磨钝程度对鑿孔速度的影响以及对鑿孔总深度的影响的试验,
In mining operations, the promotion of hard alloy bit, so far, has basically been at a stage of consolidation. How to further consolidate and give full play to its superiority, increase production efficiency, reduce production costs and accumulate large amounts of funds for industrialization of the country are the central tasks of the pilot work in the future. At present, although the “rational use of carbide drill bit, reduce production costs” test has not been thoroughly carried out, but from the grasp of the recent drill head blunt, that is, the total depth of perforation per grinding blunt, Blunt a standard degree of grinding as well as the standard number of all grinding, it is not difficult to imagine the extent of the impact of raising costs. Therefore, based on the rock conditions of the mine and based on the rock classification and the cemented carbide bit test, we conducted experiments on the influence of the degree of bluntness on the biting speed and on the total depth of the biting hole.
