Fireproof fire-extinguishing system for goaf

Abstract

The invention discloses a fireproof fire-extinguishing system for a goaf, comprising an air exhauster, a one-way valve, an air exhaust pipeline, a goaf tunnel, a fresh air pipeline, an air exhaust vertical pipe, an air exhaust transverse pipe, a nitrogen input pipeline, sensor assemblies, sealing doors, a fire extinguishing electromagnetic valve, a nitrogen storage tank and an air blower, the goaftunnel is a trampled-out area and channel in a mine, and different goaf tunnels are sealed through the sealing doors; and the sensor assemblies are installed on the sealing doors correspondingly andcomprise infrared detectors, gas sensors and humidity sensors, and meanwhile gas detectors need to be distributed and installed in the goaf tunnel at intervals. According to the invention, the internal environment is detected in real time through the sensor module; the environment in the goaf is controlled through the interaction of the air exhaust pipeline, the fresh air pipeline and the nitrogeninput pipeline, potential safety hazards are reduced, the fireproof effect is achieved, meanwhile, fire can be efficiently extinguished in time, larger-scale accidents are avoided, and the safety isgreatly improved.

Description

technical field [0001] The invention relates to the field of mining safety, in particular to a goaf fire prevention and extinguishing system. Background technique [0002] The goaf is a "hole" created by man-made excavation or natural geological movement below the surface. The existence of the goaf makes the safe production of the mine face a great safety problem. Personnel and mechanical equipment may fall into the goaf and be damaged. harm. At present, the underground empty area has become an important problem restricting the development of mines. As the mine is mined deeper, the ground pressure increases. Under the strong ground pressure, the underground empty area is prone to collapse accidents, especially for mines that are converted from underground to open pit The impact is great; a large number of stopes, chambers, and roadways left by underground mining have not been dealt with in time, which has brought serious hidden dangers to open-pit mining, and at the same ti...

Problems solved by technology

At present, the underground empty area has become an important problem restricting the development of mines. As the mine is mined deeper, the ground pressure increases. Under the strong ground pressure, the underground empty area is prone to collapse accidents, especially for mines that are converted from underground to open pit The impact is great; a large number of stopes, chambers, and roadways left in underground mining have not been dealt with in time, which has brought serious hidden dangers to open-pit mining, and at the same time posed a serious threat to mine staff and equipment

[0003] At present, the way to deal with the goaf is to block some exits of the goaf by closing doors and other structures to avoid safety hazards such as misunderstanding, but the goaf cannot be explained in time, and at the same time, there are more or less mine tunnels The existence of a part of coal and other items are still items, so there are potential safety hazards
