摘　　要：京西山区地质条件复杂,小窑浅层采空区灾害频繁,对地区工程建设及生态环境造成了严重影响和损失。小窑采空区主要灾害类型为地面塌陷及由其诱发的崩塌、不稳定斜坡和泥石流等地质灾害,灾害活动有着隐蔽性、突发性及随机性的特征,受地质构造、地层岩性、地形地貌以及气候条件、人类活动等内外地质作用因素影响,又表现出一定的客观规律。本文通过分析京西山区小窑采空区灾害特征和致灾因素,以便于开展针对性的防范措施,希望能为京西山区工程建设提供一些参考和帮助。The small coalmine gob areas disaster happens frequently in Beijing West Moun- tain area due to complex geological conditions, and had brought serious impacts and losses on the engineering construction and ecological environment. The main disaster types are land collapse and Induced disasters, such as collapse, unstable slopes, mudslides etc. and the disaster activities with characteristics of hidden, sudden and randomness. The disaster events show certain objective laws affected on influence factors that geological structure, lithology, topography,climatic conditions and human mining activities and so on. The paper according to land subside disaster characteristics and disaster--causing factors, and hope to Easy to carry out provide some references and help for the engineering construction in the west of Beijing Mountain area.
