| Abstract: |
| Scaling in mine underground drainage pipes happens frequently. In order to ensure the safe production of coal mine, the scale removal and improving efficiency of the pipes are not only the effective measures to increase the potential power of mine, but also the need for safety in mine production. By comparing with scale removal methods, the combination of chemical cleaning of static immersion and dynamic cycle cleaning is selected. Since the pipes are cleaned, the considerable funds can be saved and the production cost of coal can be reduced, which can bring very significant economic benefits to coal mine. |
