摘要
急倾斜煤层因其倾角大的缘故,很难实现正规机械化回采。急倾斜顶板管理分为松软顶板管理和坚硬顶板管理两种。走向短壁后退式仰采,它既适用于小块段的地质复杂的煤层,又能提高产量,这种采煤方法的优点是能有效地解决直接顶在回采时垮落后堵仓的问题,同时加大了生产过程中的安全性。
It is difficult to realize the formal mechanized mining due to big inclined angle in steep coal seam.Roof management in steep coal seam is divided into soft and hard roof management.The strike short-wall retreat upward mining,not only fit for the small segment coal seam with complex geological conditions,but also can increase yield.This mining method can effectively solve the blocking bunker problem in mining after caving of immediate roofs.At the same time,the safety in production is increased.
