Outline
In order to develop the measurement of hydrogen sulfide content in coal seams towards informatization，intelligence，and automation，it is necessary to innovate the measurement equipment and technical methods. By analyzing the adsorption characteristics of H2S in coal seams，the achievements in the development and application of hydrogen sulfide determination devices in recent years were summarized from the aspects of the convenience and accuracy of the construction of hydrogen sulfide determination devices. The current research status of methods for measuring hydrogen sulfide content in coal seams both domestically and internationally was elaborate. Finally，in view of the limitations of the equipment and methods for measuring hydrogen sulfide in coal seams，the future development direction of coal seam hydrogen sulfide measurement technology was discussed，and a technical system for improving the calculation error of coal seam hydrogen sulfide loss was proposed. An integrated coal sample underground crushing and desorption system，an automated desorption gas metering system，an intelligent monitoring and automated data analysis and processing system are constructed. The results show that the coal mine underground sampling method with internal and external double drill pipes，the loss of hydrogen sulfide during drilling and sampling is compensated. The measuring device is equipped with underground direct crushing equipment，filters，negative pressure vacuum tanks，and sensors for direct underground gas extraction and analysis，improving the accuracy of measuring hydrogen sulfide content in coal seams.
