急-倾斜特厚易燃煤层综放开采技术研究

Research on fully mechanized top coal caving mining technology in steep inclined ultra thick seam with spontaneous combustion in potential

针对某矿急-倾斜特厚易燃煤层进行采煤方法的改革实践,有效控制了"支架-围岩"系统的随机不稳定性,保证了矿井安全高效的生产,解决了以防灭火、防治瓦斯及防尘为核心的安全保障技术难题。对于煤矿急-倾斜特厚易燃煤层的开采具有重要的现实意义。

With the reform practices on the mining method in the steep inclined ultra thick seam, the random instability of the support and surrounding rock system was effectively controlled, which could ensure the safety and high efficient mining technology. Thus the safety protection technical problems as the key of the mine fire prevention and control, mine gas prevention and control and mine dust control were solved, which could have the important practical meaning to the coal mining in the steep inclined thick seam with spontaneous combustion in potential.
