Experimental device for researching resistivity of gas-containing coal body and use method of experimental device

Abstract

The invention discloses an experimental device for researching the resistivity of a gas-containing coal body and a use method of the experimental device. The experimental device comprises a gas guide pipe and a resistance meter; one side of the resistance meter is provided with a first constant-temperature water bath box, and the other side of the resistance meter is provided with a second constant-temperature water bath box; a gas tank is placed in the first constant-temperature water bath box; an adsorption pottery is placed in the second constant-temperature water bath box, a coal sample is placed in the adsorption pottery, an insulating cover is detachably arranged at the top of the adsorption pottery, one end of a gas guide pipe is connected with a gas tank, and the other end of the gas guide pipe is connected with the adsorption pottery. The experimental device also comprises a stabilizing mechanism. The experimental device has the beneficial effects that through the designed stabilizing mechanism, the adsorption crockery is stably placed, and the placing stability of the adsorption crockery is improved; through the designed supporting mechanism, the air guide pipe can be further supported, and the problem that a traditional air guide pipe is insufficient in supporting is solved; through the designed stabilizing assembly, the resistance meter is inclined, and the convenience for a user to operate the resistance meter is improved.

Description

Technical field [0001] The present invention belongs to the field of coal-resistance resistance, and in particular, the experimental apparatus containing gas-containing coal-containing resistivity is also related to the use of gas-containing coal resistivity research experimental devices. Background technique [0002] Geophysical exploration provides technical support for transparentization of mine production address, which can guide coal accurate mining and effectively avoid geological disasters. Among them, the electrical method exploration focuses on the characteristics representative represented by the resistivity, and reflects the properties of the medium to determine whether there is a geological abnormality. During coal mining, gas disaster is an important factor affecting safety production, and the accurate determination of coal seam gas content is of great significance for coal mine safety production. [0003] Using the principle of resistivity testing, it can be determi...
