Coal seam floor reinforcing construction structure

The utility model discloses a coal seam floor reinforcing construction structure which comprises a long-distance directional grouting hole set used for conducting grouting reinforcement on an area to be reinforced, and a high-pressure grouting mechanism arranged in a drill site and used for injecting grout into the long-distance directional grouting hole set. And the detection device is arranged in the coal seam roadway and is used for detecting the apparent resistivity of the to-be-reinforced area. The structure is simple and reasonable in design, grouting reinforcement is conducted on the to-be-reinforced area, grout injected in the grouting reinforcement process diffuses in the to-be-reinforced area and is mixed and solidified with rock mass of the to-be-reinforced area, the rock mass mechanical performance of the water-resisting layer is improved, the anti-seepage performance of the water-resisting layer is improved, the deformation resistance of the water-resisting layer is improved, and the water-resist
