一、概况在矿山勘探、供水、排水过程中,往往发生地面塌陷,对地面建筑物造成严重的危害,湖南水山口矿即是在勘探、疏干过程中,因严重塌陷而闻名,该处塌洞总数达700个以上,种类繁多,特征典型,有天然状态下的塌陷,但大多数还是因工程影响造成的,其分布范围与工程分类见图1,表1。研究塌陷的工程类型,对于供水至少有 I. Overview In the course of exploration, water supply and drainage in mines, ground subsidence often occurs, causing serious damage to ground structures. The Shuishankou Mine in Hunan is well known for its serious collapse during exploration and drainage. The total number of holes is more than 700, with a wide range of features and typical features. There are natural collapses, but most of them are caused by engineering impacts. Their distribution ranges and engineering categories are shown in Figure 1 and Table 1. Study the type of collapse of the project, at least for the water supply
