| titleOfInvention | Free drainage device of high pressure-bearing gushing water in underground roadway |
| abstract | The utility model discloses a free drainage device of high pressure-bearing gushing water in an underground roadway. The free drainage device comprises a water retaining wall, wherein the water retaining wall is provided with at least one water draining pipe; a tee valve is mounted on the water draining pipe and communicated to a central water sump on the mining level or accommodating space on the upper level; and the draining pipe is communicated to the central water sump on the mining level, a central water sump on the upper level or the ground. The free drainage device of the high pressure-bearing gushing water in the underground roadway has the benefits of low cost, simple structure and no need for electric energy, reduces use of drainage equipment or does not use a draining pump, facilitates uninterrupted drainage, and cannot be influenced by electric energy; then, a water resource is protected, and sewage treating cost is reduced; and besides, a valve can be used for controlling drainage, sampling can be performed at any time, the analysis for change of a supplement water source is facilitated, and a substantial water resource is provided for mine production. |
