| Zusammenfassung: | The utility model discloses coal-mine underground roadway type coal-seam gas-fracturing equipment, relates to the technical field of coal mine collection, in particular to the coal-mine underground roadway type coal-seam gas-fracturing equipment. The coal-mine underground roadway type coal-seam gas-fracturing equipment is characterized in that an underground coal body (5) is connected with one end of each of a plurality of high-pressure fracturing pumps (4) by a high/low-pressure manifold (6); the other ends of the high-pressure fracturing pumps (4) are connected with a fracturing-liquid blending sand mixer (2) by another high/low-pressure manifold (6); one end of the fracturing-liquid blending sand mixer (2) is connected with a plurality of liquid storage tanks (1) by another high/low-pressure manifold (6); and the low end of the fracturing-liquid blending sand mixer (2) is connected with a control monitoring device (3). The coal-mine underground roadway type coal-seam gas-fracturing equipment has the advant |
