Coal seam gas content underground direct measurement integrated device

Abstract

The invention discloses an underground direct measuring integral device for coal seam methane content. The underground direct measuring integral device comprises a shell, a hermetic smashing and desorbing tank and a processing unit, wherein the hermetic smashing and desorbing tank is arranged in the shell; the hermetic smashing and desorbing tank is provided with a pressure measuring device used for measuring the internal pressure of the hermetic smashing and desorbing tank and a temperature measuring device used for measuring the internal temperature of the hermetic smashing and desorbing tank; output ends of the pressure measuring device and the temperature measuring device are connected with the processing unit. By utilizing the underground direct measuring integral device for the coal seam methane content, which is provided by the invention, the coal seam methane content can be directly measured in an underground manner; in comparison with existing equipment, the measurement engineering quantity is small; the measurement period is short; the measurement time can be shortened to be within 1 hour; the measurement reliability and accuracy are high; the measurement process is continuous; the underground direct measuring integral device is suitable for the demands on the development of a large-scale working face and the intelligent measurement of methane parameters; the measurement on a large amount of measuring points can be carried out.

Description

technical field [0001] The invention relates to coal mine safety detection equipment, in particular to an integrated device for directly measuring coal seam gas content underground. Background technique [0002] Coal seam gas is the leading factor causing major gas disasters such as coal and gas outburst, abnormal gas gushing, and gas explosion. Accurately grasping the occurrence law of coal seam gas is the premise of preventing and controlling gas outburst. Therefore, accurate measurement of coal seam gas content is crucial important. [0003] At present, there are mainly two methods for measuring coal seam gas content, namely indirect method and direct method. The indirect method is to establish a model relationship between the gas content and coal seam parameters, measure the coal seam parameters on site, and measure the gas content through the model relationship. This method has high cost and long measurement cycle, which may have a certain impact on production. The di...
