煤矿顶板管理工作历来是煤矿安全生产工作重要内容。历年来的安全状况表明,顶板事故占有相当大的比例,因而,抓好顶板管理是促进煤矿安全生产的重要基础工作。而对于急倾斜煤层开采来说,顶板管理工作更为重要,它不仅要管好煤层顶板,而且要管好煤层底板。伪倾斜正台阶采煤法在磨田井试验成功,不仅推动了我矿急倾斜煤层采煤方法的改革步伐,而且在顶板管理方面取了成功经验,从而大大减少了回采工作面顶板事故的发生,确保了煤矿安全生产。 Coal mine roof management has always been an important part of coal mine safety work. The safety status over the years shows that the roof accidents occupy a considerable proportion. Therefore, to grasp the roof management is an important basic work to promote coal mine safety production. For steep seam mining, roof management is even more important. It not only manages the coal seam roof but also manages the seam floor. Pseudo-tilt positive step coal mining method in the mill wells successfully tested not only promoted the pace of coal mine steep coal mining method of reform, but also in the roof management has taken the successful experience, thus greatly reducing the occurrence of roof mining accidents, To ensure the safety of coal mines.
