摘要

According to the distribution of coal resources, the coal seam with a large dip angle occupies a high proportion, and the mining of this kind of coal seam is paid more and more attention. But it is very difficult to mine because of its big dip angle, big thickness change, and brittle and easy caving. How to overcome these difficulties effectively and realize the safety mining of large inclined coal seam is an important research topic in the field of coal seam mining. In this paper, firstly, the characteristics of high inclined coal seam are summarized and based on the characteristics of the coal seam, the mining methods of this kind of coal seam, and the equipment used in the development of high inclined coal seam in China are summarized. Secondly, according to the difficulties of the mining coal seam, the mining theory and technology put forward by predecessors when solving these difficulties are summarized. Finally, combing the previous work related to the maintenance of coal seam safety, and put forward the prospects for future safety monitoring.
