The hole packer may be used to inject water into the coal seam to loosen the coal seam and to improve the coal exploration and coal seam organization. When water is injected into the coal, it can wet and break the coal body, so that some gas will be released. It can reduce the concentration of coal gas and dust by 80% or better. In this way, it can improve the operating environment and helps to reduce the hazards of fire and ensure the safety underground.
