冲击回转钻进能提高钻进效率和钻孔质量,减少事故,降低成本,又可有效地解决硬岩钻进中的“打滑”问题.因而近来在国内得到较快的推广.到目前为止,研制出来的冲击回转冲击器已有一、二十种,为今后的合理选用提供了条件.1982年5月,安徽省地矿局321队与云南地矿局技工学校一起,在冬瓜山矿区,对SX-53-Ⅲ型射吸式液动冲击器和Z F-56型正作用液动冲击器进行了对比试验.
Impact rotary drilling can improve the drilling efficiency and the quality of drilling, reduce accidents and reduce costs, but also effectively solve the “slippery” problem of hard rock drilling, which has recently been in the country to get a faster promotion.So far, Developed out of the impact rotary impact device has one or two, for the future of the rational use of conditions provided.In 1982 May, 321 Bureau of Geology and Mineral Resources Anhui Province and Yunnan Bureau of Geology and Mineral Resources Institute of mechanization in the mining area, Dongguashan, right SX-53-Ⅲ type of suction-type hydraulic impactors and Z F-56-type positive impact was carried out a comparative test.
