近年来，苏联液动冲击钻进的使用范围极大地扩大了，在Ⅳ到Ⅻ级岩层中液动冲击钻进勘探孔的深度可达1200米，直径为115、93、76及59毫米。由于“地质技术”科学生产联合企业所属专门设计局研制成高频液动冲击器，液动冲击钻进的使用范围扩大到软和极硬岩层，当配有成批生产的硬质合金钻头可有效地钻进Ⅳ—Ⅵ级岩层，而用成批生产的金刚石钻头可钻进Ⅹ—Ⅻ级硬岩层。
In recent years, the use of liquid percussion drilling in the Soviet Union has been greatly expanded. The depth of the liquid-percussion drilling exploration holes in the IV to Ⅻ rock formations can reach 1200 meters with diameters of 115, 93, 76 and 59 mm. Due to the development of high-frequency hydraulic impactors by the specialized design bureau of the “Geotechnical” scientific production joint venture, the use of hydraulic impact drilling is extended to soft and extremely hard rock formations. When equipped with batch production of carbide drills Grade IV-Ⅵ rock formations are effectively drilled, while bulk rock drill bits can drill into Ⅹ-Ⅻ grade rock formations.
