摘要
为了适应地下矿山高阶段大直径深孔采矿的需要,长沙矿山研究院、凡口铅锌矿、昆明冶金机械厂共同研制了 CGW-150型高风压潜孔冲击器和钻头。1986年开始这项研究工作,1989年初投入现场工业试验。
In order to substitute imports with domestic ITH drill and button bit,changsha Institute of Mining research in cooperation with Fan Kou Lead- Zinc Mine and Kun Ming Metallurgical Equipment Manufactory developed a new model ITH drill and button bit In this paper the author briefly described the structure design and basic technical parameters of the ITH drill and bit,as well as the experimental results in high sublevel blasthole stopes.The experi- mental results shown that the new Model ITH drill and bit in performance, drilling effeiciency and service life was comparable to abroad similar products.
