試验的目的为了进一步提高鑿岩速度和更有效地使用硬質合金钎头,降队鑿岩成本,必需改进現有的鑿岩工具——釺头的結構。这項工作在苏联有專門的研究机構进行过一些改进試验,从1953年开始在各矿山先后作过生产試验,并在試验中改进了合金片的形狀,获得了一些经验。在我国过去几年中先后也进行过少量的試验研究工作,但是,由于合金片的形状和質量不能滿足試验的要求,这一工作还未进行过较大数量的生产試验,所以釺头的改进还待研究。
The purpose of the experiment In order to further improve the drilling speed and the more effective use of carbide drill bit, down the cost of rock drilling, the existing rock drill tool must be improved - This work carried out some improvement tests in the Soviet Union with specialized research institutes. Since 1953, it has successively conducted production tests at various mines and improved the shape of the alloy flakes in the experiment, gaining some experience. In the past few years in our country, a small amount of experimental work has also been carried out. However, since the shape and quality of the alloy flake can not meet the requirements of the test, this work has not yet been carried out in a relatively large number of production tests, Still to be studied.
