在1970～1980年期间,曾研制出装有取岩芯钻管的地质钻探用的风动冲击器。可是,这种风动冲击器在多年冻结砂矿区地质钻探工程中并未获得广泛应用,因为经过管外空间排出的废气沿孔壁产生上升气流,引起孔壁融化和塌落。在这种情况下试图使用普通潜孔风动冲击器也发生过类似现象。 During 1970-1980, pneumatic impingement devices for geological drilling equipped with core drill pipe have been developed. However, this type of pneumatic impactor has not been widely used in geological drilling projects in the frozen sand mining area for many years because the exhaust gas discharged through the outer pipe space produces ascending airflow along the hole wall, causing the wall to melt and slump. A similar phenomenon has also occurred in attempts to use common downhole aerodynamic impactors in such situations.
