摘要
在“八五”计划确定之际为正确选型并确定新型钻机的研制开发方向，必须对各类钻机进行科学的比较评价。而在比较时，一方面要考虑钻机技术性能的优劣、可靠性和机械化程度等；另一方面还需考虑不同时期各类钻机生产、销售的数量、比率及其变化，并要注意不同类别市场中各型钻机占有率的实际情况。本文介绍了有关液压钻机、动力头钻机的统计数字及交流变频驱动钻机的最新进展情况，据此对今后我国新型地质岩心钻机的研制方向提出了具体意见。
: Making scientific comparision and appraisal of the various types of core drill are
essential to orienttaing further development of new-type core drills. For the comparision, there are
two aspects should be considered. One is the characteristics, reliability and mechanized level of a
core drill. The other is the amount of produced and sold, the ratio of sale and production and its
change tendeney, esp.the real occupation market of various drills. The statistical figures concerned in
this paper are hydraulic drills,top-head drills as well as the naw developed AC drive drills. In view of
the above, the developing trand of new core drills in China will be proposed.
