| titleOfInvention | Maintenance of slurry explosive pumping assembly for successive loadings |
| abstract | The invention provides method, and system, for automatically removing residual slurry explosive from a delivery conduit, or hose, of a slurry explosive pumping-loading assembly, after each loading, to maintain the assembly operable during a series of successive loadings. Thus, after the loading, residual slurry explosive is evacuated from the delivery hose while the hose remains extended into the emplacement zone and into the resulting mass of emplaced explosive therein, by introducing a gas (generally air) into the hose for displacement of the residual slurry into the emplaced slurry mass, and automatically terminating introduction of said gas into the hose in response to addition of a predetermined amount of the gas sufficient for the displacement. The system includes means for introduction of the displacement gas into the hose, and means for maintaining the gas in displacement flow; and means for terminating the gas introduction in response to addition of the predetermined displacing amount. In preferred practice, and as specifically illustrated, the invention terminates the gas flow in response to expiration of a predetermined time required for the displacement. The invention, by automatic termination of the displacement gas flow, eliminates human error inherent in manual operation to prevent concomitant, and often violent, flow of excess displacement gas into the emplaced slurry and to thereby eliminate resulting impairment of the emplaced explosive properties encountered in manual operation heretofore. |
