Abstract2013-07-17T20:00—2013-07-18T3:00,冕宁县牦牛坪稀土矿区7 h降雨219 mm,瓦维埃河及支沟发生6处水石流,对采矿场、选矿厂、地面站、弃土场、排洪沟、矿山公路及矿山环境造成严重危害。研究发现:牦牛坪矿区具备水石流发育的充分条件,泥石流沟处于发育壮年期,但泥石流处于衰退期。"7·18"水石流是在100 a一遇强暴雨激发下,沟床及岸坡老泥石流堆积物和沟床堆积物在山洪冲蚀下切、侧蚀下形成的,暴雨和水石流暴发频率同步。其水石流具有固体物质粗大(最大粒径8 m),块砾石含量高(80%以上),粉、粘粒含量极低(小于1%),容重高(1.6-1.85 t/m3),冲淤变化大(最大冲深10 m,最大淤积5 m),规模大(总冲出量50×104m3)等特点。
