接杆凿岩技术,自五十年代以来,就已成为我国不少地下矿山矿石回采作业中,钻凿爆破中深孔的主要手段之一。近年来,在掘进工程中也得到了应用。随着国产YG—80型、YZ-90型凿岩机的出现,特别是在CZZ—700型自行轮胎式凿岩台车和CTC-214型双机采矿台车推广使用以后,我国现阶段的接杆凿岩技术又有了新的发展。但是,做为接杆凿岩的主要工具之一中深孔凿岩钎头,其生产技术仍然停留在五十 Since the 1950s, post rock drilling technology has become one of the main means of deep hole drilling and blasting in the mining operations of many underground mines in our country. In recent years, it has also been applied in excavation projects. With the advent of domestically produced YG-80 and YZ-90 rock drill machines, especially after the promotion of the CZZ-700 self-propelled tire drilling rig and the CTC-214 dual-purpose mining vehicle, the current post of our country Drilling technology has a new development. However, as one of the main tools of post rock drilling deep hole rock drilling head, its production technology remains at fifty
