Hydraulic filling method

(1) Stage transportation and flat roadway - According to the specific conditions of the mine, the ore body of the rock deposit will change greatly, and the annual output required by the design is also large. In order to adapt to the rationality of the filling pipeline, the lower disc is adopted. Pingxiang, Shuangping Lane ring-collecting system on the upper plate of the pulse. (The typical plan is the Zhimaiping Lane).

(2) through the vein roadway - every 15 to 20 meters to open a pulse. The veins are arranged at the high boundary of the mine and the column, and the mine and the column share a vein. This arrangement saves the amount of mining work by arranging a pulse through each of the mine room columns.

(3) Flow mines - According to the length of the mine, at least two mines should be arranged in one mine.

(4) Filling wells - A filling well is arranged in the middle of the mine. The section is 2 × 2 m ² and the inclination is 80 ° ~ 90 °. The pipe side and the ladder are set. It is one of the safety exits.

(5) Pedestrian dewatering wells - A mine has a dewatering well. Its structural requirements are: should meet the requirements of water discharge.
