第四代钻机综述
-
摘要: 多功能钻机,目前在澳大利亚、美国、法国、南非等国的工程勘探中已广泛应用,不仅提高了勘探进度,而且降低了生产成本,保持了工程投标的竞争能力,技术经济效益显著。多功能钻机的研制成功,能用一台钻机即可在多种场地和多种工作条件下用不同的钻进方法进行地质勘察工作。有的国家正研制新一代微机辅助操作的自动化钻机,这种新型的自动化和多功能钻机的研制成功,将对未来的钻探技术产生深远的影响。Abstract: The drilling machine with multifunctions is widely used in the engineering surveying in Australia、America、France and south-Africa. It can be used in varied sites and varied conditions by using different drilling method. The automatic drilling machine controlled by computer assistant system is studied in some countries. It can be very significant to future drilling technique.
