Abstract

The invention discloses a similar simulation system of the coalfield fire spreading process and relates to the technical field of similar simulation. A physical similarity model is installed in an experiment box and comprises a lower covering heat-insulation rock stratum, a coal seam and multiple upper covering rock stratums. The coal seam is heated through heating bars, a plurality of sheathed thermocouples are embedded in the lower covering heat-insulation rock stratum, the coal seam and the upper covering rock stratums. Temperature parameters detected by the sheathed thermocouples are collected by a multi-point temperature detector and analyzed by a computer, combustion conditions of coalfield fire areas under different conditions are simulated by changing the heating temperature, the number, the type and heating positions of the heating bars, and practicality is high. The continuous and real-time monitoring function is achieved by means of the high-sensitivity temperature sensing function of the sheathed thermocouples, the signal collection conversion function of the multi-point temperature detector and the analysis function of the computer.

Description

technical field [0001] The invention relates to the technical field of similar simulation, in particular to a similar simulation system for coalfield fire evolution process. Background technique [0002] Coalfield fires refer to combustion accidents that occur within mines or coalfields, threaten safe production, cause certain resource and economic losses, or cause casualties. Coalfield fires widely exist in Northwest China, and are one of the main disasters threatening coal mining in Northwest China. Spontaneous combustion of coal causes a large amount of burning loss of underground coal resources, reduces the reserves of coal resources, threatens the safe production of coal mines, and seriously affects my country's energy development strategy to the west. The existence of coalfield fires has also caused a large number of environmental and ecological problems, and relevant technical measures must be taken to curb the continued spread of coalfield fires. [0003] At presen...
