    • In the method of the invention a laterally expandable retainer (302) is provided. This is of smaller length than the hole (1609) and has an inlet (303) at a lower end thereof and an outlet at an upper end thereof. In an unexpanded state the retainer has a smaller lateral dimension than the hole. The retainer is inserted upwardly into the hole in an unexpanded state, whereafter material with which the hole is to be charged is pumped upwardly into the retainer through the inlet such that the retainer fills up and expands laterally into engagement with a wall of the hole. Excess pumped material is allowed to upwardly out of the retainer into the hole through the outlet. After the retainer has been filled with material and the hole above the retainer has been at least partially filled with any excess material, the pumping operation is stopped and the inlet is closed. The material is then retained in the hole by engagement of the filled and expanded retainer with the wall of the hole. Another aspect of the invention concerns the apparatus used in the method.
    • 在本发明的方法中,提供了横向可扩张的保持器(302)。 其长度小于孔(1609),并且在其下端具有入口(303),在其上端具有出口。 在未膨胀状态下,保持器具有比孔更小的横向尺寸。 保持器在未膨胀状态下向上插入孔中,此后将要将孔充入的材料通过入口向上泵入保持器,使得保持器填充并横向膨胀以与孔的壁接合。 允许过多的泵送材料通过出口向上通过定位器进入孔。 在保持器已经填充材料之后,保持器上方的孔已经至少部分地被任何多余的材料填充,泵送操作停止并且入口被关闭。 然后通过填充和扩张的保持器与孔的壁的接合将材料保持在孔中。 本发明的另一方面涉及该方法中使用的装置。

    • One aspect of the invention concerns a method of charging an upwardly oriented hole with a pumpable material, typically a pumpable explosive material such as an ANE. In the method of the invention a laterally expandable retainer is provided. This is of smaller length than the hole and has an inlet at a lower end thereof and an outlet at an upper end thereof. In an unexpanded state the retainer has a smaller lateral dimension than the hole. The retainer is inserted upwardly into the hole in an unexpanded state, whereafter material with which the hole is to be charged is pumped upwardly into the retainer through the inlet such that the retainer fills up and expands laterally into engagement with a wall of the hole. Excess pumped material is allowed to upwardly out of the retainer into the hole through the outlet. After the retainer has been filled with material and the hole above the retainer has been at least partially filled with any excess material, the pumping operation is stopped and the inlet is closed. The material is then retained in the hole by engagement of the filled and expanded retainer with the wall of the hole. Another aspect of the invention concerns the apparatus used in the method.
    • 本发明的一个方面涉及一种用可泵送材料(通常为可泵送的爆炸性材料例如ANE)向上取向的孔填充方法。 在本发明的方法中,提供了横向可膨胀的保持器。 其长度小于孔的长度,在其下端具有入口,在其上端具有出口。 在未膨胀状态下,保持器具有比孔更小的横向尺寸。 保持器在未膨胀状态下向上插入孔中,此后将要将孔充入的材料通过入口向上泵入保持器,使得保持器填充并横向膨胀以与孔的壁接合。 允许过多的泵送材料通过出口向上通过定位器进入孔。 在保持器已经填充材料之后,保持器上方的孔已经至少部分地被任何多余的材料填充,泵送操作停止并且入口被关闭。 然后通过填充和扩张的保持器与孔的壁的接合将材料保持在孔中。 本发明的另一方面涉及该方法中使用的装置。
