摘 要: 在分析陕北浅埋沟壑区特殊地形条件下开采塌陷灾害特征的基础上,将塌陷灾害划分为崩塌、坍塌、滑坡、台阶裂缝4种灾害类型。以陕北矿区冯家塔矿为工程背景,通过分析灾害形成的基本条件,应用层次分析法(analytic hierarchy process,AHP)结合试验模拟结果,建立AHP评价模型。根据灾害形成的条件,提出应用协调开采、局部限高开采、局部充填开采的方法减缓开采塌陷灾害的强度,为该条件下开采塌陷灾害防治提供了依据。
关 键 词: 采矿工程;浅埋煤层;沟壑区;塌陷灾害;灾害防治

Abstract: Based on analyzing the characteristics of mining collapse disaster in the special terrain condition of shallow mining seam gully region in Northern Shaanxi province, slough disaster is divided into avalanche, collapse, landslide and step crack. Taking Fengjiata Coal Mine in Northern Shaanxi province mining area as the engineering background, through analyzing the basic conditions of slough disaster, and combined with the experimental simulation results, related theory of analytic hierarchy process (AHP) is used to establish AHP evaluating model. It proposed that it should use coordinated mining, local limited height mining, partial backfill mining to slowdown the mining collapse disaster strength according to the disaster formation conditions. The results can provide scientific basis of mining collapse disaster prevention for similar mining conditions.
Key words: mining engineering; shallow seam; gully region; collapse disaster; disaster prevention
