| Abstract: | The No.2 seam in Lingwu Mining Area is an ultra thick seam with high tenacity, easy to be combusted and hard to be falling. After the analysis on the physical mechanism features and natural spontaneous combustion features of the ultra thick seam, the deep borehole blasting soften technology for the top coal and the comprehensive fire control technology have been successfully applied to the fully mechanized top coal caving mining in ultra thick seam with high tenactity, easy combusted and difficult falling in Ciyaobao No.2 Mine. The application of the technology has obtained predicted results. |
