Coal mine intelligent fire preventing and extinguishing integrated grouting device and method

Abstract

The invention relates to the technical field of coal mine grouting, in particular to a coal mine intelligent fire preventing and extinguishing integrated grouting device. The coal mine intelligent fire preventing and extinguishing integrated grouting device comprises a mixing barrel, a plurality of raw material bins, a conveying pipeline, a data acquisition device, a monitoring center, a mixing system and a pre-arranged industrial control looped network. The mixing system comprises the mixing barrel and a mixing controller; a conveying pump is mounted at the output end of the mixing barrel; the data acquisition device comprises a pipeline detection module; the pipeline detection module is integrated on the conveying pipeline; a gas acquisition module and a temperature measurement module are in communication connection with the data acquisition device; the gas collection module collects the concentration of carbon monoxide in a grouting drill hole; the temperature measurement module measures temperature information in the grouting drill hole; and the data acquisition system is in communication connection with the monitoring center through the industrial control looped network. According to the coal mine intelligent fire preventing and extinguishing integrated grouting device, intelligent grouting for self-adaptively adjusting the grouting pressure, the grouting flow and the grouting time is realized under the condition of inherent grouting drilling parameters, and the whole equipment can be moved, so that the better overall effect of coal mine fire preventing and extinguishing prevention and control work is achieved.

Description

technical field [0001] The invention relates to the technical field of grouting in coal mines, in particular to an intelligent integrated grouting device and method for fire prevention and extinguishing in coal mines. Background technique [0002] Fire safety is particularly important in the underground mining process of coal mines; the mechanism of preventive grouting fire prevention in coal mines is: after making a slurry of non-combustible solid materials and water in a certain proportion in advance, the static pressure generated by the height difference or the dynamic pressure of the mud pump Under the action of the special slurry pipeline, it is pressed to the area where the fire may occur. After the solid slurry material in it settles, it wraps the broken coal body with the help of its viscosity, and isolates it from contact with oxygen to prevent oxidation. And the slurry material is filled between the cracks of the broken coal body, which can increase the compactness...

Problems solved by technology

In the prior art, during the grouting process in coal mines, the proportion of raw materials in the grouting liquid, the pressure, flow and time of grouting are only judged by manual experience, and there is a problem that insufficient grouting affects safety
