问题的提出钎具(钎头、钎杆或整体钎子等)是凿岩工的必备工具,其对采掘工程的影响,不能仅仅理解为钎具消耗能量的多寡和钎具费用的高低,而应当着重看到优质钎具对于缩短凿岩时间、加快工程进度、降低工程造价、改善工人作业条件所带来的全部好处。包括:钎具消耗量和钎具费用的节省;硬质合金和钢材等原材料的节省;凿岩时间缩短引起的凿岩辅助费用(气、水、电等动力消耗,相关设备和机具折旧,劳动工资等)的节省;峻工期提前以及工人劳动、安全、卫生条件改善所诱发的全部社会政治经济利益。因此,优质钎具除重视坚固性所体现的寿命因素外,尤其关注破岩和排粉效率所体
The question put forward Brazing tools (drill bits, drill rods or brazing, etc.) are indispensable tools for rock drillers. Their impact on mining engineering can not be understood simply as the amount of energy consumed by brazing tools and the cost of brazing tools. Instead, it should focus on the advantages of high-quality brazing tools for shortening the drilling time, accelerating the progress of projects, reducing the construction costs and improving the working conditions of workers. Including savings in brazing tool costs and brazing tool costs; savings in raw materials such as cemented carbide and steel; drilling assistance costs due to shortening of drilling time (power consumption of gas, water, electricity, depreciation of related equipment and machinery, labor Wages, etc.) savings; advanced construction period and all the social and political economic benefits induced by the improvement of workers’ labor, safety and sanitation. Therefore, the quality of solder with emphasis on durability in addition to reflect the life factor, with particular attention to broken rock and discharge efficiency of the body
