Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] An embodiment of the present invention provides a device for collecting radon migration parameters in the porous medium of coal and rock mass. The device can collect the concentration value of radon after migrating in the porous medium of coal and rock mass. Migration parameters. The device takes full account of various factors affecting the migration of radon, such as coal quality, rock quality, soil quality, temperature, humidity, particle size, migration direction, and the influence of other gases on the migration of radon. Practical environment for migrating underground.
[0021] refer to figure 1 and figure 2 As shown, the device includes a base 1, the base 1 is hollow inside, and the lower part is a horizontal base. Th...

The invention provides a collection device of migration parameters of radon in coal-rock mass porous media. The device comprises a base which is provided with a migration channel module, the migration channel module comprises a double-layer sealing migration pipe body which comprises an inner pipe and an outer pipe, and the inner pipe is filed with coal-rock mass; one or more gas detection pipes are evenly arranged on the migration pipe body in the axial direction, and the gas detection pipes are connected with a multichannel radon detection gas chromatographic instrument. The device further comprises an angel control module, a temperature control module and a gas delivery module. By means of the collection device of the migration parameters of the radon in the coal-rock mass porous media, real time collection can be conducted on the migration parameters, the real environment of migration of the radon in a mine is simulated to the maximum extent, various factors affecting radon migration are fully considered, it is guaranteed that the migration parameters of the collected radon in the coal-rock mass porous media have better scientificity and practicability, and the detecting precision of detection of a hidden fire source position in a coal bed through a radon detecting method is improved.
Description
technical field [0001] The invention relates to the technical field of collecting migration parameters of radioactive substances, in particular to a device for collecting migration parameters of radon in porous media of coal and rock mass. Background technique [0002] Coal is one of the important energy sources for the world's economic and social development, so the safe mining of coal is very important. Since coal will spontaneously ignite when certain conditions are met, and coal seam fires are highly concealed, it is difficult to accurately determine the location of high-temperature spontaneous combustion areas, resulting in the lack of pertinence in the fire prevention and extinguishing techniques used, and it is difficult to effectively control and prevent coal seam spontaneous combustion, wasting a lot Therefore, research on the detection technology of the high-temperature area of spontaneous coal combustion has a positive effect on the prevention and control of coa...
