Zhongtian industrial mine high pressure high flow 2BZ-125/20 briquette seam injection pump 2BZ-125/20 briquette seam injection pump uses high-pressure, high-flow pulsating high-pressure water to act repeatedly on the coal body in a short period of time, so that the coal body continues to expand and contract, leading to coal fatigue damage, the strong surface of the coal body is weakened, the weak surface of the coal body is further extended, so as to achieve the increase in the degree of coal breakage, the coal body Increased connectivity of fractures Therefore: 1. It is mainly used for water injection in various types of coal seams, especially difficult to inject water into coal seams; it is an effective technical means of solving water injection in coal seams with low permeability and high hardness. /2. Short-term high-strength coal seam water injection enhances the connectivity of coal cracks and weakens the strength of the coal body, effectively improves the breathability of the coal body, and releases the concentration of local stress in the coal body. It has a positive effect on improving the gas extraction effect of coal seam, reducing the risk of coal and gas protrusion, and preventing impact ground pressure. Technical characteristics of coal seam water injection pump: 1.
