Description

Technical Field

[0001] The invention belongs to the technical field of coal mine security, and in particular relates to a device for preventing and controlling spontaneous combustion of coal seams used in coal mines. Background Art

[0002] At present, coal mines have adopted a variety of methods in fire prevention and extinguishing technology, including grouting fire prevention and extinguishing, colloid fire prevention and extinguishing, pressure equalization ventilation fire prevention and extinguishing, inhibitor fire prevention and extinguishing, inert injection fire prevention and extinguishing and foam fire prevention and extinguishing. These technologies each have unique characteristics and advantages, aiming to effectively prevent and control the occurrence of coal mine fires;

[0003] Among them, grouting fire prevention and extinguishing technology is a common fire prevention and extinguishing method, which is mainly used in spontaneous combustion risk areas such as mine goafs. This technology injects gel, three-phase foam and other substances into these areas to form an isolation layer to prevent the occurrence, development and extinguishing of coal spontaneous combustion. This technology has been widely used in mines with serious coal spontaneous combustion, especially high-yield and high-efficiency mines and high-gas and self-igniting coal seams.

[0004] The Chinese invention patent with the authorization announcement number CN114961825B discloses a pressure-equalizing fire prevention control system and fire prevention method for a protruding coal seam mining working face, which relates to the ventilation field of mines or tunnels. The control system includes an air intake lane air control component: an air intake door and an air intake, and an air supply device for quantitatively supplying air through the air intake; a return air lane air control component: a return air door and a return air intake, and a regulating device for regulating the exhaust air volume through the return air intake; a monitoring control system, a signal acquisition unit, a control processor, and a manual control device for instantaneous door opening. This system constructs a pressure-equalizing ventilation system through a special structure and control logic to ensure the required ventilation air volume for the working face and prevent toxic and harmful gases from rushing into the working face; the pressure-equalizing damper is opened at the moment of gas outburst to achieve full-pressure ventilation and avoid the reversal of a large amount of outburst gas, thus solving the problem that pressure-equalizing fire prevention and extinguishing measures cannot be used on the working face of mining outburst coal seams. This invention achieves partial control over the spontaneous combustion of coal seams by controlling the ventilation volume, but in actual use, some naturally ignited coal seams still need to be extinguished by spraying liquid.
