西场村崩塌发生于2010年8月5日夜间,崩塌体位于林州市石板岩乡桃花洞西场村的西北山体的半山腰部位,崩塌山体岩性为石灰岩,坡脚高程1000m左右,崩塌危岩顶面高程约1200m,坠落高差约200m。山坡总体坡度75°～85°,山前斜坡坡角45°～50°,坡长100m左右,山体坡脚处有树林、农田、旅游公路和居民点,属小型岩质崩塌。崩落的块石一部分堆积于坡面,另一部分崩落于河谷和农田中。目前,山体上还分布着较多未崩落的危岩和斜坡上崩落的浮石约4500m3,崩塌危岩高度约80m,最大宽度约25m,最大厚度约12m,呈倒锥形态,母岩为寒武系灰岩,崩塌体积约4500m3,崩落最大水平距离约130m,最大块度3m×3m×3m。本次产生崩塌的山体在1990年曾对山体危岩进行过爆破清理,但危岩未脱离母岩坠落,所以,当年的爆破清危与本次山体崩塌有着直接的关系。
The collapse of Xicui village occurred on the night of August 5, 2010. The collapsed body was located on the hillside of the northwestern mountainous area of Nishimura, Peach Blossom Cave, Shilian Township, Linzhou City. The rock mass of the collapsed mountainous area was limestone, Dangerous rock top elevation of about 1200m, elevation difference of about 200m. The overall slopes of the slopes are 75 ° ~ 85 °, the slope angles of the front slopes are 45 ° ~ 50 ° and the length of the slopes is about 100m. There are woods, farmland, tourist roads and settlements at the foot of the mountain slopes. Some of the rock falling from the piles is piled up on the slope and the other part collapses into valleys and farmland. At present, there are still more unoccluded dangerous rock and caving pumice on the slope about 4500m3, height of collapsed rock about 80m, maximum width of about 25m, the maximum thickness of about 12m, inverted cone morphology, the parent rock is Cambrian Department of limestone, the collapse of the volume of about 4500m3, the maximum horizontal distance caving about 130m, the largest block 3m × 3m × 3m. In 1990, the mountain that had collapsed was subjected to blasting and cleaning of the rock mass, but the rock mass was not separated from the rock mass. Therefore, the blasting hazard in that year was directly related to the collapse of this mountain.
