Embodiment Construction
[0024] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0025] A full potential energy terminal pipeline transportation paste filling system for coal mining, comprising:
[0026] Pulp making equipment for adding water to cement and fly ash to make slurry, the slurry may also include other substances other than cement and fly ash;
[0027] Gangue supply equipment, which can transport gangue underground;
[0028] The slurry conveying pipe 21 is used for conveying the slurry underground;
[0029] The filling pipe 25 is connected with the gangue supply equipment and the slurry conveying pipe 21. The filling pipe 25 can mix the slurry and the gangue in the filling pipe 25 and guide it to the branch lane 27 to be filled. The fil...

The invention provides a coal mining full-potential tail end pipeline conveying paste filling system and method. The system comprises slurrying equipment, gangue feed equipment, a slurry conveying pipe (21) and a filling pipe (25), and slurry and gangue can be mixed in the filling pipe (25) and led to a branch roadway (27) to be filled. According to the coal mining full-potential tail end pipeline conveying paste filling system and method, gangue, cement, flyash and other filling materials wide in source are fully used, pipeline filling is adopted in the position close to the working face, condition adaptability is high, and efficiency is high. According to the coal mining full-potential tail end pipeline conveying paste filling system and method, energy generated by potential energy in the natural world is used, energy generated by investment equipment is reduced, and filling cost is greatly reduced.
Description
technical field [0001] The invention relates to the field of mining technology, in particular to a paste filling system for full potential energy terminal pipeline transportation in coal mining, and a paste filling method for coal mining full potential energy terminal pipeline transportation. Background technique [0002] At present, the mines mined by the backfill method in China can be divided into fully mechanized face gangue solid filling, general mining face gangue solid filling, and fully mechanized mining according to coal mining technology, working face filling equipment and filling location. Face (similar) paste filling or (super) high water filling, general mining face (similar) paste filling or (super) high water filling, coal road crawler self-propelled gangue thrower solid filling and other filling forms. [0003] Backfill mining is mainly restricted by three conditions, namely backfill material, backfill efficiency and backfill cost. SUMMARY OF THE INVENTION ...
