Problems solved by technology
In short, it is to do its best to extract and exhaust; on the other hand, adopt technologies such as plugging, pressure equalization, inert gas, inhibitors, three-phase foam, polymer materials, polymer foam and other technologies to prevent and control coal spontaneous combustion. The prevention and control of coal seam gas disasters has played a certain role, but with the increase of coal mining depth, the difficulty of coal seam gas prevention and control has gradually increased, and the gas and fire disasters have become more serious

The invention provides a biotechnology prevention and control gas and fire symbiosis disaster simulation experiment device and method, including a gas injection system, a liquid injection system, an air extraction system and a temperature and pressure measurement system respectively connected to a pressure-resistant and heat-insulated test box. The gas injection system includes oxygen cylinders, nitrogen cylinders and methane cylinders arranged side by side. The liquid injection system includes a biological agent configuration box. The air pump is connected to a gas chromatograph, and the temperature and pressure measurement system includes a plurality of temperature measuring probes and temperature testers arranged in the pressure-resistant and adiabatic test box, and also includes a pressure sensor arranged in the pressure-resistant and adiabatic test box. The temperature measuring probe is connected to the temperature tester through the thermal resistance wire bundle, and the temperature tester, the pressure sensor and the gas chromatograph are all connected to the computer analysis system. The device of the invention has simple structure and convenient data collection, and can provide a data basis for other related experimental researches on the disaster-causing mechanism of gas and fire symbiotic disasters.
Description
technical field [0001] The invention relates to the experimental field of prevention and control of coal mine gas and fire symbiotic disasters, in particular to a simulation experiment device and method for preventing and controlling gas and fire symbiotic disasters by biotechnology. Background technique [0002] According to the survey, nearly one-third of the coal mines in the country have the risk of symbiotic disasters caused by high gas and coal spontaneous combustion. At present, the most direct means of prevention and control of co-occurrence disasters are: on the one hand, adopt various pre-mining, mining and post-mining drainage measures for gas drainage, and use auxiliary measures such as deep hole blasting, hydraulic fracturing, hydraulic slotting, etc. Pressure relief and antireflection. In short, it is to do its best to extract and exhaust; on the other hand, adopt technologies such as plugging, pressure equalization, inert gas, inhibitors, three-phase foam, po...
