Long-distance colloid slurry filling device

The utility model relates to a long-distance colloid slurry filling device, comprising a pump station and a coal layer fire-proof drilling point which are connected together by a mine fire-control slurry filling device, characterized in that the pump station is composed of two injection pumps and the injection pump (1) is connected with a solution mixer (5) near to the drilling point by a lower-lane fire-proof slurry filling pipe (3) of an under-well work surface and the injection pump (2) is connected with the solution mixer (5) by a lower-lane standby fire-proof slurry filling pipe (4) of the under-well work surface and the solution mixer (5) is connected with the coal layer fire-proof drilling point (6). The advantages of the utility model are that: the long-distance colloid slurry filling device thoroughly solves the problem that traditional colloid slurry filling technology is easily limited by the narrow space of the digging work surface and the material transmission and device installation are difficul
