煤矿工业面临着矿井工作环境复杂、瓦斯安全事故频发的现状。目前，瓦斯监测技术还存在预警能力弱、智能化程度低、准确度低和系统可靠性低等缺点，严重制约着煤矿工业向安全、绿色和高效方向发展。针对煤矿工业的现实需求，本项目提出研究一种“基于柔性光栅与柔性驱动的全光型煤矿瓦斯红外吸收光谱检测”新思想。项目将研发光驱动柔性光栅变形进行光谱扫描检测、光驱动微泵等新技术，最终实现矿井下瓦斯浓度全光型、远程、快速、准确探测。该技术方案中矿井下仅有光学器件，无电源等电子器件，消除了电路短路、放电等故障对矿井安全的潜在威胁。项目将探明这种新思想的检测原理和方法、各种影响因素对检测精度的影响规律，最终建立一套远程、全光型的瓦斯实时监测系统的原型样机。该新方法具有检测精度高、系统稳定可靠、成本低等优势，适于大面积应用，将为煤矿工业等危险行业提供一种廉价、先进的检测方法和技术，具有重要的理论和实际意义。

Considering complex environment of the mine, accidents of safety in production happening in coalmine frequently, and low reliability of the gas monitoring and controlling system, monitoring coal-mine gas rapidly and accurately is extremely necessary for developing the safety of coal-mining industry effectively. the major detecting method is currently simple equipment based on gas sensors and gas safety monitoring system, however, its properties, including low forecast ability, low degree of intelligence and low reliability, make it impossible to achieve mine safety production. Therefore, a new technique with optical-actuated flexible grating and gas pump –“Methane Gas Monitoring Based on Infrared Absorption Spectrum” is presented in this project. This method has the advantage of detecting the coal-mine gas rapidly and accurately, the mine without power source, and eliminating the short circuit and open circuit. The detection principle of this new technique and the influence of various factors on the detecting accuracy are ascertained. And a monitoring system will be built to validate the proposed principle and method, which lays a solid foundation for the practical application. The proposed research with high detection accuracy, high reliability and low cost will overcome the drawbacks of the current mine gas detection methods (Low degree of intelligence and low accuracy). The study provides theory basis for the application of the low-cost and advanced method in coal-mining industry and other related industry. And hence, it is of great theoretical and practical significance.
