合理提高急倾斜综放工作面水平分段高度的探讨

水平分段综合机械化放顶煤是开采急倾斜特厚煤层较好的现代采煤方法,合理提高水平分段高度是必要的,技术上是可行的,经济上是合理的。通过采取有效的安全技术措施能够保证系统安全,并能够确保回采率完成。通过提高段高,能有效缓解采掘接续紧张的矛盾,实现矿井的集约化联合开采,使建设千万吨级的急倾斜煤层开采矿区成为现实。

Probing into Rational Improvement of Horizontal Sublevel Height of Steep-pitch Fully-mechanized Caving Face

Horizontal sublevel fully mechanized caving mining is a better modern coal mining method for steep-pitch seams.To rationally improve the horizontal sublevel height of steep-pitch fully mechanized face is essential,technically feasible and e-conomically rational.Taking effective safety and technical measures can guarantee the system's safety and ensure the recovery coefficient.The improvement of the horizontal sublevel height can effectively mitigate the contradiction of mining and development continuance,realize the intensively combined mining of a mine and enable the steep-pitch coal mining area with a capacity of 10 million tons to become true.
