摘　　要：综述了目前国内水力化措施、二氧化碳爆破、高压空气爆破及电脉冲冲击波等增透技术的研究进展。分析了这些技术在研究和运用当中存在的问题,指出这些技术基础理论研究不完善、配套装备不完整及并未形成规范的技术标准等因素制约了这些技术的推广使用。对煤层增透技术进行了展望,认为要根据地质条件来采取合理的增透技术,同时配套相应的装备将更加安全、方便、可靠,并形成一整套基础理论体系和编制相应的操作规程及应急处理方案。This paper overviewed the research progress of hydraulic technology, carbon dioxide blasting, high pressure air blasting, electric pulse stress waves and other permeability improvement technology. Through analyzing the problems of theoreti- cal research and engineering application of these techniques, this paper found that many factors restricted the wide application of these techniques, such as imperfectness of the theory basis, incompleteness of the equipment and none of normative technical standards. This paper took a expectation for the development tendency of permeability improvement technology and suggested that it was safer, more convenient and reliable to take reasonable permeability improvement technology according to geological conditions and combined with the corresponding equipment, and to form complete series of basic theoretical system and compile corresponding operation rules and emergency treatment plan.
