摘要:

为使煤层硫化氢含量测定朝着信息化、智能化、自动化方向发展,需革新测定装置及技术方法。首先通过分析硫化氢在煤层中的吸附特性,从硫化氢测定装置构造便捷性、精确性等方面总结近年来测定装置研发及应用方面取得的成果;然后阐述国内外煤层硫化氢含量测定方法的研究现状;最后基于煤层硫化氢测定装置及方法的局限性,展望未来煤层硫化氢测量技术的发展方向,提出完善煤层硫化氢损失量计算误差的技术体系,构建煤样井下一体化破碎解吸系统、解吸气体自动化计量系统、智能化监测与自动化数据分析处理系统等。结果表明:采用内外双钻杆的煤矿井下取样方法,可补偿钻进取样过程中硫化氢损失量;测定装置配备井下直接粉碎设备、过滤器、负压真空罐及传感器,可用于井下直接抽气,以提高煤层硫化氢含量测定的准确性。

Abstract:

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.

Key words: coal seam hydrogen sulfide content, loss amount, measurement devices, measurement methods, intelligentization
