摘要（英）：

The invention discloses a simulation test device and method for a rodlike additive for coal seam water injection, and belongs to the technical field of coal mining dust prevention. The simulation testdevice comprises an electric pressure test pump, a simulation water injection pipeline, a water tank, a support frame, a first high-pressure hose, a second high-pressure hose and a surface interfacial tension meter. The right end of the first high-pressure hose is connected with the left end of the simulation water injection pipeline through a flange; the right end of the simulation water injection pipeline is connected with the left end of the second high-pressure hose through a flange; the right end of the second high-pressure hose is arranged in the water tank, and each of the first and second high-pressure hoses is provided with a valve; the second high-pressure hose is provided with a flow meter; the simulation water injection pipeline is provided with a pressure recorder. The invention also provides a simulation test method of the rodlike additive for coal seam water injection. The simulation test device provided by the invention can test the solubility of a solid rodlike additive under different water pressures and different effluent flow rates. The surface tension of a solution is measured to optimize an additive formula.
