Problems solved by technology

[0003] During the grouting process, when the grouting material in the goaf increases, the polluted flue gas in the gob or the injected grouting material will float upwards, generating a certain impact force, and the grouting pipe is easy to be damaged by the impact force. Shaking under the action of the grouting will affect the grouting, and at the same time, it may cause the outflow of the grouting material or the polluted smoke. The outflow of the grouting material will cause waste, and the outflow of the polluted smoke will pollute the environment, which is not conducive to environmental protection. Therefore, We propose an environmentally friendly auxiliary fixture for goaf grouting and its operating method

Abstract

The invention discloses an environment-friendly auxiliary fixing device for goaf grouting and an operation method thereof, and belongs to the field of goaf grouting. The environment-friendly auxiliary fixing device for goaf grouting comprises a stirring tank and a conveying tank, and a grouting pipe is in threaded connection with the interior of a rotating disc; an inner pipe is arranged in the grouting pipe, an auxiliary part and an air cylinder assembly which are matched with each other are connected in the grouting pipe, the outer wall of the grouting pipe is connected with an air bag, and the air bag is in communication with the air cylinder assembly; and a pin is further connected into the grouting pipe in a sliding mode. According to the environment-friendly auxiliary fixing device, grouting materials can be stirred to be convenient to convey, the grouting pipe can be connected more stably through the air bag and the pin, the air bag is attached to the inner wall of a grouting hole after being expanded, the grouting materials cannot be discharged and blocked, waste caused by overflowing is avoided, and polluted smoke can only rise along the grouting pipe, the polluted smoke is prevented from being discharged into air through a gap between the grouting hole and the grouting pipe, the environment is prevented from being polluted, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of environment-friendly grouting, in particular to an environment-friendly auxiliary fixing device for goaf grouting and an operation method thereof. Background technique [0002] The goaf is a "cavity" created under the surface by human excavation or natural geological movement. The existence of the goaf makes the safe production of mines face great safety problems. [0003] During the grouting process, when the grouting material in the goaf increases, the polluted flue gas in the gob or the injected grouting material will float upwards, generating a certain impact force, and the grouting pipe is easy to be damaged by the impact force. Shaking under the action of the grouting will affect the grouting, and at the same time, it may cause the outflow of the grouting material or the polluted smoke. The outflow of the grouting material will cause waste, and the outflow of the polluted smoke will pollute the envi...
